Profit Loss Question

2012-01-26T16:39:00.000-08:00

Profit Loss is a relatively easy topic and quite often gets tested in these kinds of entrance tests.

Question

If the cost price of 12 articles is the same as the selling price of 10 of those articles, what percent profit does the trader make?
1. 16.66%
2. 20%
3. 25%
4. 16.66% loss
5. 20% loss

Correct Answer: Choice (2) - 20% profit.

Explanatory Answer

Let the cost of 12 articles = Rs.x

Hence, the cost of 1 article = x/12

So, the selling price of 10 articles = Rs.x

Hence, the selling price of 1 article = x/10

The quickest way to solve this question is to assume some value for x. Assume x to be a number that is divisible by 12 and 10.

So, x should be a multiple of 12 and 10. Take x to be 120.

So, the cost of 12 articles = 120. Therefore, the cost of 1 article = Rs.10

The selling price of 10 articles = 120. Therefore, the selling price of 1 article = Rs.12.

The profit on 1 article = Selling price - Cost price = 12 - 10 = Rs.2

Percent Profit = (Profit / CP) * 100 = (2/10)*100 = 20%

Speed Distance Time : TANCET Quant

2011-12-12T22:11:00.000-08:00

Speed Distance Time is one of the topics from which you should expect a question either in the quantitative reasoning section or in the data sufficiency section of the TANCET MBA.

Here is a relatively easy quantitative reasoning question from this topic

Question

It takes Kiran 50 minutes lesser to cover a distance if she travels three times as fast as she does now. How long will she take to cover the distance if she travels twice as fast as she does now?
1. 50 minutes
2. 75 minutes
3. 150 minutes
4. 100 minutes
5. 37.5 minutes

Correct Answer : Choice 5. 37.5 minutes

Explanatory Answer

Let Kiran's present speed be S km/min. And let her take t minutes to reach her destination.

If Kiran travels three times as fast as she does now i.e., at 3S, she will cover the same distance in 1/3 of the time i.e., in t/3 minutes.

So, she is saving (t - t/3) minutes = 2t/3 minutes.
The question states that she is saving 50 minutes.
Therefore, 2t/3 = 50
or t = 75 minutes.

If she travels at S km/min, she will reach her destination in 75 minutes.

So, if she travels at 2S km/min, she will take half that time = 75/2 minutes = 37.5 minutes.

TANCET Math - Ratio Proportion

2011-11-08T21:11:00.000-08:00

Hi

Ratio proportion is an often tested area in the quant section of the TANCET MBA exam. I have posted a medium level difficulty question on Ratios.

Question

The sum of the ages of 3 friends is 90 years. If 5, 3 and 2 years are subtracted respectively from the ages of the oldest, middle and the youngest the ratio of their ages becomes 8 : 5 : 3. What is the age of the oldest of the 3 friends?
1. 40
2. 48
3. 28
4. 17
5. 45

Correct Answer : 45 years. Choice 5.

Explanatory Answer

Let the age of the 3 friends be a, b and c - a the oldest, b the middle one and c the youngest.

Therefore, a + b + c = 90

The question states that a - 5 : b - 3 : c - 2 :: 8 : 5 : 3
So, a - 5 + b - 3 + c - 2 = 8k + 5k + 3k
Or a + b + c - 10 = 16k ... eqn (1)
Substituting a + b + c = 90 in eqn (1), we get 90 - 10 = 16k
or 16k = 80
Hence, k = 5.

a - 5 = 8k
or a - 5 = 40
Therefore, a = 40 + 5 = 45 years.

Angles in a triangle : TANCET Geometry

2011-09-16T04:51:00.000-07:00

Geometry, specifically triangles is an oft tested area in the TANCET quant section.

Here is a relatively easy question on triangles.

If the largest angle in a triangle is 70^o, what is least possible value of the smallest angle of the triangle?

1) 69
2) 1
3) 40
4) 39
5) 41

The correct answer is 40.

Explanatory answer

The sum of the interior angles of a triangle is 180.

The question states that the largest of the angles is 70.

We are interested in finding the least possible value of the smallest of the three angles.

The least value for the smallest angle will be when the other two angles are as large as possible.

The largest value that the other two angles can take is 70 each.

Therefore, the least value of the smallest of the angles = 180 - 70 - 70 = 40

TANCET Quant : Linear Equations, Word Problems

2011-08-22T00:31:00.000-07:00

Here is a word problem that requires you to frame a pair of linear equations, solve the equations to arrive at an answer.

Rajesh is 10 years younger to Baskar. 10 years back, Rajesh's age was two-thirds that of Baskar's. How old is Baskar now?
1. 30
2. 40
3. 20
4. 16
5. 28

Correct Answer is Choice (2). 40 years.

Explanatory Answer

Let the present age of Baskar be 'b' and that of Rajesh be 'r'.
So, r = b - 10 .... eqn (1).

10 years back Rajesh was (r - 10) years old. 10 years back Baskar was (b - 10) years old.
The question states that 10 years back Rajesh was two thirds as old as Baskar was.

i.e., (r - 10) = (2/3)*(b - 10) .... eqn (2).
Cross multiplying, we get 3(r - 10) = 2(b - 10)
or 3r - 30 = 2b - 20 .... eqn (2)

From eqn (1) we can substitute r as (b - 10) in eqn (2)
So, 3(b - 10) - 30 = 2b - 20
or 3b - 30 - 30 = 2b - 20
or b = 40.

The present age of Baskar is 40 years.

Word problems : Linear Equations

2011-05-18T20:11:00.001-07:00

You should anticipate a question that expects you to convert information presented in words into an equation and solve it.

They are commonly referred to as "word problems". The key to getting those questions right is to try and decode the information in the sentence and frame equations accordingly.

Here is a question that will give you an idea of how to frame a linear equation from the information given in the question statement.

If the result of seven more than four times a number is tripled, the resultant number is three more than fifteen times the number. What is the number?
1. 6
2. 7
3. 4
4. 15
5. 12

TANCET Math : Averages

2011-01-20T01:27:00.000-08:00

Averages is an oft repeated topic in TANCET quant section. You may also get a variant of questions from the arithmetic mean and weighted average concept as Data Sufficiency Questions in TANCET.

Here is a sample averages question. A rather easy one.

Average weight of 25 boys in a class is 48 kgs. The average weight of the class of 40students is 45 kgs. What is the average weight of the 15 girls in the class?
1. 44 kgs
2. 42 kgs
3. 40 kgs
4. 39 kgs
5. 42.5 kgs

Speed Distance Time Question TANCET

2011-01-15T03:37:00.000-08:00

Speed, Distance and Time is an important topic from a TANCET quant perspective. You could expect to get one to two questions from this topic.

The core concept in this topic is the relation between these three parameters
Distance = speed * time.

The second point to keep in mind while solving questions from this topic is to check if the units of the three parameters match.
i.e., if distance is measured in kilometres and time in hours, speed should be in km/hr. Alternatively, if speed is in kilometres and time in minute, speed should be in km/min.

Here is an easy to moderate level difficulty question in this topic.

A bus travels at 40 kmph for the first 100 kms, 60 kmph for the next 100 kms and 48 kmph for the final 200 kms, what is the average speed over the total distance?
1. 48 kmph
2. 50 kmph
3. 49 kmph
4. 52 kmph
5. 50.4kmph

The concept tested in this question is that of average speeds.

The answer to this question is 48 kmph.

Explanatory Answer

Average speed for the first 200kms = 2ab/(a + b) = 2 * 40 * 60/(40 + 60) = 48 kmph.

Bus travels equal distances at two different speeds, average speed = 2ab/(a + b)

Now, if we break the overall journey into two stretches of 200 kms each, the bus travels the first 200kms at 48kmph, and the second at 48 kmph. Overall, average speed = 48 kmph.
Correct answer (1)

Alternatively, you could find out the total time taken to cover the entire distance of 400 kms

Time taken for the first 100 kms = 100 / 40 = 10/4 hours

Time taken for the second 100 kms = 100/60 = 10/6 hours

Time taken for the last 200 kms = 200/48 = 50/12.

Adding up all three, we get 10/4 + 10/6 + 50/12 = 100/12 hours.

Average speed = total distance / total time

= 400 /(100/12) = 4800/100 = 48 kmph

TANCET Quant : Percents

2010-12-18T06:55:00.000-08:00

Here is a relatively easy question from the topic Percents.

Question

If A is 40% more than B and C is 68% more than B, what percent is C more than A?
1. 28%
2. 17%

3. 20%
4. 10.8%
5. 54%

TANCET Quant : Progressions

2010-10-22T21:03:00.000-07:00

AP, GP (Arithmetic Progressions and Geometric Progressions) are two topics from which you could expect to get at least one question.

An interesting topic and the kind of questions that you can expect in the TANCET quant section from these two topics will be rather elementary.

The AP topic has two formulae to remember.

The first one is to find the nth or the last term 'l' of an AP : l = a + (n - 1)d, where 'a' is the first term, n is the number of terms and 'd' is the common difference.

The second formula is to find the sum of first 'n' terms of an AP. Sn = (n/2)(2a + (n - 1)d)

Here is a question that tests your understanding of these concepts.

If the first term of an AP is 12 and the 7th term is 36, what is the sum of these 7 terms?

1. 240

2. 168

3. 336

4. 84

5. 121

Explanatory Answer

The first term a = 12

The 7th term l = 36.

We know that l = a + (n - 1)d

or 36 = 12 + (7 - 1)d

or 24 = 6d

or d = 4.

Sum of these first 7 terms = (n/2)(a + (n - 1)d), where n = 7, a = 12, d = 4

Substituting we get, (7/2)(2*12 + (7 - 1)4)

= (7/2)(24 + 24)

= 7 * 24

= 168

Choice (2) is the correct answer.

Speed Time Distance : TANCET Math

2010-01-19T02:48:00.000-08:00

Speed, Time and Distance is an interesting topic from which you could expect to get one question in the math section and probably a question in the data sufficiency section of the TANCET MBA test.

The concept is extremely simple : Distance = Speed * Time
The place where you need to be careful is to make sure that the units that you use for the different quantities have integrity i.e., if the unit for speed used is km/hr, then you should use hour as the unit for time.

Here is a simple question in speed time distance.
Question
Traveling at 4/5ths of her usual speed, Sonal reached office 20 minutes late. How long did she take today?
1. 60 minutes
2. 80 minutes
3. 100 minutes
4. 64 minutes
5. 96 minutes

Explanatory Answer
She travels at 4/5th of her usual speed.
Let her usual speed be 's' km/min. So, today she travels at 4/5s.
Let the usual time she takes be 't' minutes. So, today she will take (t + 20) minutes.
As the distance traveled in both the cases is the same, we can equate them
i.e., st = 4/5s (t + 20)
dividing both sides by 's' we get t = 4/5(t + 20)
or 5t = 4t + 80
or t = 80 minutes.
t is the usual time take.
The time taken today is t + 20 = 100 minutes.

Note: 1. We used km/min as the unit for speed as the unit of time given in the question is in minutes.
2. we did not stop at finding the value of 't'. The question was about finding the time taken today = t + 20.

TANCET Math : Work Time

2010-01-10T21:26:00.000-08:00

Hi

Here is a work time question. You could expect a question on this topic. A topic that gets usually tested in the test.
Question
A works twice as fast as B does and together they complete a task in 8 days, how long will A lone take to complete the task?
1. 16 days
2. 4 days
3. 32 days
4. 12 days
5. 24 days

Correct Answer
Choice (4). 12 days.

Explanatory Answer
A works twice as fast as B does.
So, if B does 'x' units of work in a day, then A does 2x units of work in a day or in a day they do 3x units of work.
Together, they complete the task in 8 days.
i.e., in a day together they complete 1/8th of the total task.
3x = 1/8th of the task.
So, x = 1/24th of the task.
We know A does 2x units of work a day = 2 * (1/24) = 1/12th of the work in a day.
So, A will take 12 days to complete the task.

TANCET Quant Practice Questions

2009-12-09T00:17:00.000-08:00

I am providing links to webpages where you can get free practice questions for TANCET Math section.

These links are organized on a chronological order.

August 2003 : You will find a lot of Number Theory, Number Properties and Averages questions in this collection.

Ratio Proportion on Ages

2009-11-01T23:58:00.000-08:00

A favorite question that appears more often than not from the Ratio Proportion topic is that of comparing the ages of two people.

Here is an example of such a question.

Question

The ratio of the present ages of Shreyas and Swetha is 3 : 5. Six years back Swetha was twice as old as Shreyas was. How old is Shreyas now?

1. 24
2. 12
3. 30
4. 18
5. 36

Correct Answer is choice (4). 18 years

Explanatory Answer

Let the present age of Shreyas be x years and that of Swetha be y years.
Therefore, x : y :: 3 : 5

Or x/y = 3/5
or x = (3/5)y. --- eqn (1)

6 years back Shreyas was (x - 6) years old.
6 years back Swetha was (y - 6) years old.

We know that Swetha was twice as old as Shreyas was 6 years back.
So, (y - 6) = 2(x - 6) --- eqn (2).

Substituting x = (3/5)y from eqn (1) in eqn (2) we get
(y - 6) = 2((3/5)y - 6)
or 5(y - 6) = 2(3y - 30)
or 5y - 30 = 6y - 60
or y = 30.

x = (3/5)y = (3/5)*30 = 18 years.

Quadratic Equation : Roots of equation

2009-04-08T02:24:00.000-07:00

You could expect to get a question from quadratic equation in the TANCET test.

A quadratic equation is an equation of the form ax² + bx + c = 0.

Each quadratic equation has 2 roots. The roots of the quadratic equation can be found out either by factorizing the equation or by using a formula.

If r₁ and r₂ are the roots of the quadratic equation, then
r₁ = (-b + root(b² - 4ac))/2a
r₂ = (-b - root(b² - 4ac))/2a

Here is a typical question in quadratic equation
Question
If 8 and 6 are the roots of a quadratic equation, then the equation is
(1) x² + 14x + 48 = 0
(2) x² - 14x + 48 = 0
(3) x² + 14x - 48 = 0
(4) x² - 14x - 48 = 0
(5) x² + 48x + 14 = 0

If we are given the roots of a quadratic equation, i.e., r₁ and r₂, then the quadratic equation is (x - r₁)(x - r₂) = 0.
We know that the roots of equation are 8 and 6.
Hence, the equation is (x - 8)(x - 6) = 0
or x² - 14x + 48 = 0

Mensuration question

2009-03-21T01:05:00.000-07:00

Question
What is the total surface area of a right circular cylinder in sqcm if its base diameter is 14cm and height is 12cms?
1. 528
2. 308
3. 836
4. 1144
5. 4576

Correct choice (3). Correct answer is 836 sqcm

Explanatory Answer
Total surface area of a right circular cylinder is 2*pi*r*h + 2pi * r^2
Base diameter of the cylinder is 14cm.
Hence, its base radius is 7cm.
Therefore, total surface area is 2*(22/7) * 7 * 12 + 2*(22/7)*7^2
= 528 + 308 = 836

Mensuration is a relatively easy topic to master. Learn all the common formulae for volume, surface area, total surface area of solids such as right circular cylinder, right circular cone, sphere, hemisphere. Solve 10 to 12 questions, at least, for each of the formulae and you should be able to ace questions from this topic.

TANCET 2009 Announcements

2009-03-11T04:31:00.000-07:00

TANCET 2009 will be conducted on May 30th for TANCET MBA and TANCET MCA and on May 31st for TANCET ME/M.Tech

You have just over 2 months from today (March 11, 2009) for the TANCET examination. Actually, if you focus on your preparation earnestly from this moment, you have enough and more time to ace the exam.

An open category student with over 50 marks in the TANCET test in 2008 would have got admission into leading MBA programs that come under Anna University such as Guindy Engineering College, PSG Tech, SSN, TSM Madurai and so on.

Scoring 50 in TANCET is both easy and tough. It is easy if you solve over 1000 math questions, 200 plus Reading comprehension passages, 400 odd sentence correction questions and practice with 4 or 5 mock TANCET tests. It is tough because not more than 25 students have scored that kind of marks in the year 2008.

TANCET, thankfully, has been a predictable exam with clearly set 5 sections, with 20 questions to each section. Break down what you have to learn for each section and spend time wisely - about 3 to 4 hours a day from now to get into the college of your choice.

Lastly, all of us know that the whole world, including India, has been facing a lot of economic challenges. Campus placements are not great this year. Even if you manage to get placed - one is not sure if you will actually convert your offer letter into actually joining the company. So, at least temporarily, the good times (easy placements) are gone. In such trying times, the wise thing to do is to join a PG program and weather the economic downturn in a college / university. When you graduate in 2011, the economy is bound to bounce back and you will most likely be flooded with offers. So, get started with your TANCET Preparation.

A quick way to compute weighted average of large numbers

2009-02-04T00:28:00.000-08:00

Hi

Weighted average is an easy concept that gets test quite often in the quantitative section of the TANCET test.

Let us take a look at a question that requires you to compute the weighted average and then evaluate an alternate shorcut approach to computing the same.
Question
If the average marks scored by 30 students of school A in Class XII board exam is 1072 and that by 20 students of school B is 1084, then what is the average marks scored by the students of the two schools taken together?
1. 1078.6
2. 1076.8
3. 1075.9
4. 1080.2
5. 1077.

Correct Answer
Choice (2). 1076.8

Explanation
The conventional way to solve this question is to find the weighted average of the two marks as show below.
(30*1072 + 20*1084)/(30 + 20)
= (32160 + 21680) / 50
= 53840 / 50
= 1076.8.

As you realize, conceptually there was nothing difficult with solving this question. The only pain point was the calculation. And it might not be possible for most of us to solve this calculation in under 1.2 minutes.

Now let us look at an alternate, shortcut approach to this question.
Step 1: Subtract 1072 from both 1072 and 1084.
Step 2: Compute the weighted average of the resulting numbers. i.e. ,0 and 12
The weighted average of 30 students scoring 0 and 20 students scoring 12
= (30*0 + 20*12) / (30 + 20) = 240 / 50 = 4.8
Step 3: Add 1072 to the weighted average obtained in step 2. i.e., 1072 + 4.8 = 1076.8

Therefore, whenever you have to compute the weighted average of two large numbers, subtract the smaller of the two numbers from both the numbers and then compute the weighted average and then add back the subtracted number to the result.

TANCET Prep Qn: Ratio Proportion

2009-01-19T04:47:00.000-08:00

Ratio proportion is a fundamental topic from which you should expect anything from 2 to 3 questions out of the 20 questions in the Math section of TANCET MBA test.

The following question is a ratio question and tests your ability to express one term in terms of another, given the ratio between the two terms.

Question
Sum of the ages of three friends is 98 years. If the ratio of the ages of the oldest to the middle is 5 : 3 and that of the middle to the youngest is 5 : 3, how old is the oldest?
1. 49 years
2. 50 years
3. 30 years
4. 32 years
5. 42 years

The correct answer is 50 years. i.e., Choice (2).

Explanatory Answer
One of the easiest approach to solve this question is outlined below

Let A be the oldest, B the middle one and C the youngest amongst the three friends.
Ratio of the ages of A and B, A : B :: 5 : 3
i.e., A/B = 5/3
Therefore, A = (5/3) B

Ratio of the ages of B and C, B : C :: 5 : 3
i.e, B/C = 5/3.
Hence, C = (3/5)B

We also know that A + B + C = 98

Rewriting the equation in terms of B, we get (5/3)B + B + (3/5)B = 98.
Taking 15 as the common denominator and adding we get (25B + 15B + 9B)/15 = 98
Or (49/15)B = 98
Or B = (98*15)/49 = 30.

Hence, age of A = (5/3)B = (5/3)*30 = 50 years.

2008-12-02T00:05:00.000-08:00

Linear Equations is one of the fundamental topics from which you could expect one or two questions in the TANCET test.

A Linear Equation is one in which the power or the exponent of the variable is 1. An equation of the form 3x + 2y = 17 is a linear equation.

A linear equation in two variables x and y represents a straight line when plotted on a x - y plane. The equation of the x-axis is y = 0 and that of the y-axis is x = 0.

The following question is a word problem in linear equation. You will be presented some information as a statement and you will be expected to fram linear equation based on the information provided there and solve the linear equation to get the answer.

Question
QuestionRam's father is thrice as old as Ram. 6 years hence, his father will be 24 years older than Ram. How old is Ram?
1. 24 years
2. 18 years
3. 12 years
4. 36 years
5. 42 years

Correct Answer and Explanation
Let Ram's present age be R.
So, his father's present age is 3R.

6 years hence, Ram will be (R + 6) years old
6 years hence, Ram's father will be 3R + 6 years old.
The question states that 6 years hence, Ram's father is 24 years older than Ram.
i.e., 3R + 6 = (R + 6) + 24

Or 3R + 6 = R + 30
or 2R = 24 or R = 12.
Ram's present age is therefore 12 years.

Shortcut Approach
You should actually solve this question by going back from the answer choices. That way, you will save a lot of time. Anyone who is serious about cracking the TANCET should commence your preparation for the TANCET exam not later than the day your fifth semester exams are over if you are in a 3-year degree program or after your seventh semester exam gets over if you are in a 4-year degree program.

Work - Time questions

2008-11-25T22:07:00.001-08:00

Work Time is topic that gets tested in the quant section of both TANCET MBA and TANCET MCA tests. It is an easy topic, if one had understood the basics of the Work Time questions.

Let us say Ram completes a task in 10 days. And Lakshman takes 15 days to complete the same task. A typical question will expect us to find out the time taken when both Ram and Lakshman work together.

The first temptation is to just add the two values 10 and 15 and say 25. However, that does not make sense. If Ram alone could complete the work in 10 days, then when Lakshman helps him, it should take lesser than 10 days.

So, we have to find an alternative approach to answer this type of questions in TANCET.

When Ram and Lakshman work together the amount of work done in a day will be the sum of the work done by Ram in a day and that done by Lakshman in a day.

If Ram takes 10 days to complete a task, then he will complete 1/10th of the task in a day.
Similarly if Lakshman takes 15 days to complete a task, then he will complete 1/15th of the task in a day.

Now, if Ram and Lakshman worked together they will complete 1/10 + 1/15 of the task in a day.

Now, that translates to 5/30th or 1/6th of the task getting completed in a day.
This certainly makes sense as higher amount of work gets done when the two of them work together.

If Ram and Lakshman complete 1/6th of the work in a day, then the entire task will be over in 6 days (the reciprocal of the amount of work done by them in a day).

Now let us summarize the method to solve work time question:

1. The reciprocal of the time that the first person takes to complete a task is the amount of task completed by the first person in a day.

2. Find the amount of work done by the second person in a day in the same way.

3. Add the amount of task completed when the two of them work together. i.e., add the result of step 1 and step 2.

4. To find the amount of time that the two will take when they work together, find the reciprocal of the answer obtained in step 3.

Try this question

If 'A' can complete half the work in 12 days and 'B' can complete half the work in 18 days, how long will they take to complete the entire task if they worked
together?

1. 30 days
2. 60 days
3. 7.2 days
4. 14.4 days
5. 21.6 days

Weekly Math prep question for TANCET MBA

2008-11-24T04:57:00.000-08:00

I will periodically post interesting questions similar to those that are tested in the TANCET MBA and TANCET MCA tests.

As you are aware a fifth (i.e.,) 20 questions out of the 100 questions in the TANCET MBA paper is the math or the quant section. And about 60 questions out of the 100 questions in TANCET MCA paper is the math or the quant section.

The math that is tested in both the TANCET MBA and TANCET MCA sections are 10th standard level math.

Be assured that you will not see any of the 12th standard level math questions such as Calculus, Matrices, Vectors etc., as this exam is open to even students who would not have taken math in class 12.

In effect, what TANCET math tests is Arithmetic, Basic Algebra, Geometry topics. For good measure get yourself acquainted with Modern math topics such as Permutation Combination and Probability and Set theory if you want to score high in this section.

TANCET Exam is conducted in the second or third week of May every year. If you are keen on cracking the test, then you should start your TANCET Preparation about 3 to 6 months before the test date.

Profit Loss Question

If the cost price of 12 articles is the same as the selling price of 10 of those articles, what percent profit does the trader make? 1. 16.66% 2. 20% 3. 25% 4. 16.66% loss 5. 20% loss

Correct Answer: Choice (2) - 20% profit.

Explanatory Answer

Let the cost of 12 articles = Rs.x

Hence, the cost of 1 article = x/12

So, the selling price of 10 articles = Rs.x

Hence, the selling price of 1 article = x/10

The quickest way to solve this question is to assume some value for x. Assume x to be a number that is divisible by 12 and 10.

So, x should be a multiple of 12 and 10. Take x to be 120.

So, the cost of 12 articles = 120. Therefore, the cost of 1 article = Rs.10

The selling price of 10 articles = 120. Therefore, the selling price of 1 article = Rs.12.

The profit on 1 article = Selling price - Cost price = 12 - 10 = Rs.2

Percent Profit = (Profit / CP) * 100 = (2/10)*100 = 20%
