Watch the below video to learn Tips & Tricks to crack Questions on Simplification and Approximation in Campus Recruitment Exams.

The Following questions are based on Simplification and Approximation:

Simplification involving Large Numbers:

1. -87+1934-271-?=893

A.679

B.683

C.687

D.689

Explanation:

From the given question  Do you notice all the option are very close to each other

Do you notice except the first and last option remaining two options have a different unit digit at the end of the number

Now we have to take the unit digit of each number along with the sign

-7+4-1-?=3

Instead of taking the 4 we have to take 14 or 24 and so on

Because if we take the number 4 it will get negative digits. But our answer is in positive

So, we have to take 14 instead of 4

-7+14-1-?=3

6-?=3

In the place of the question mark,  the number 3 has to come

According to the option, the unit digit which ends with 3 is 683.

2. 12738-2314-1781+9816=?

A.18459

B.18461

C.19459

D.19461

Explanation:

First part

Look at the following options 459&461 are repeated two times

The unit digit could be 1 or 9

Based on that we have to eliminate two options

Second part

The unit digit of each number will be

8-4-1+6=9

we need the number ending with '9'

so, 2&4 options are eliminated

Now we are Looking at the thousand terms

12-2-1+9=18

It will be 18000

Third part

Suppose if we have two options starting with 18 and the units place is 9 we have to use the third part

From the above question, we have two 7 hundred numbers if they are canceled it get -50 or -40 difference

Then 816 & -314 it will get 500 difference(18000-50+500)

So, the answer is approximately equal to 18,450

Simplification involving Fractions

3. 3 4/5+5 6/7=

A.9 23/35

B.9 24/35

C.9 25/35

D.9 33/35

Explanation:

First, we have to consider

3+4/5+5+6/7=8+0.8+5+0.85≈9.65

Then 9 ?/?

we know that denominator should be 5 or 7 or 35

For the safe, you have to assume 35

then 9 ?/35

The numerator will be 23 or 24 or 25

Because of the fraction should be 0.65

But in the given options numerator has given 23,24,25

so we have to find  given numerator

3+4/5+5+6/7=8+(28+30)/35=8+1+23/25=9 23/35

4. 3 4/5+? 3/8=9 ?/40

A.5,6

B.4,8

C.5,7

D.4,7

Explanation:

Here 9 ?/40 in this '?' should be less than 40

Step 1 Isolate the whole & fraction

3+4/5+x+3/8+=9+?/40

Step 2 Estimate the whole number

3+4/5+x+3/8+=9+?/40

'x' should be equal to 5 due to '9'

Step 3 Simplifying the fraction

4/5+3/8=(32+15)/40=47/40=1+7/40

Here 7/40 is the fraction

5. 4 3/7-8 2/5+6 1/5-7 4/7=?

A.-4 15/35

B.-5 12/35

C.-5 15/35

D.-4 12/35

Explanation:

whole numbers                 fractions

4                                        +3/7

-8                                        -2/5

Watch the below video to learn Tips & Tricks to crack questions on percentages topic in Campus Recruitment Exams by Adhitya Lanka (IIM-Calcutta) having 10+ years of experience in Teaching Quantitative Aptitude and Reasoning

The following questions based on percentages:

Calculation Based Questions:

1. What is 38.3% of  647 +  51.1% of  943?

A.687

B.729

C.773

D.813

Explanation:

Where the hint is: the options are not very close to each other. So, you can find the approximate value easily.

Now, 38.3% of  647 = 40% of  650  (take near values to the actual Values because options are not very close)

51.1% of  943 =  50% of  940

Where,  40% of  650 is 260  (10% of  650 is 65→ So, 40% of  650 is 260)

50% of  940 is 470 ( 10% of 940 is 94→ So, 50% of 940 is 470)

→   260+470 = 730

730 is near to 729. Hence option B) 729 is the answer

Multiplication factors on Profit and Loss

2. A shopkeeper purchased a chair in the second-hand market for Rs.837. He then invested 1/5th of the amount in getting it painted and packaged. He priced it in such a way that he gets a 60% profit. Eventually, the article had to be sold at a discount of 20%. What is the overall profit or loss percentage?

A. 20% loss

B. No loss No profit

C. 20% profit

D. 28% Profit

E. 33.6% Profit

Explanation:

CP = Rs. 837

1/5 of Rs. 837 = Rs. 167.4 spent on painting and packaging.

Hence, total CP = 837 + 167.4 = Rs. 1004.4

P% = 60 % which is equivalent to SP = 1.6 when CP = 1.

But, d of 20 % provided — Hence, final SP  will be 0.8 x 1.6 or 0.8 x 1.6 x 1004 = Rs. 1285 approximately.

Then, the Profit = SP - CP = 1285 - 1004 = Rs. 281 and profit % = 28 % making option D as the answer.

Difference between SI and CI

3. A person lent a sum of money at 12% per annum SI and received an interest of 2700 at the end of 2 years. What would be the interest if the same sum was invested at 12% per annum Compound Interest?

A. 2700

B. 2661.12

C. 2738.88

D. 2958.74

Explanation:

A = P(1.12)2 = P(1 + 0.12)2

= P(1 + 2*0.12 + 0.0144)

= P(1 + 0.24 + 0.0144)

= P + 0.24P + 0.0144P

CI should be greater than  SI. So, A.2700 and B. 2661.12 are not considered as CI. When we calculate above then we may get at most 100 extra then D.2958.74 is also not considered as CI.  Hence only C. 2738.88 is the suitable answer because it is greater than and near to SI

Mix and Match - Find a rate

4. A salesperson sold 40% of his wares at a profit of 5%. At what profit % should he sell the remaining goods to get an overall profit of 11%?

A.15%

B.20%

C.25%

D.30%

Explanation:

Let the amount invested for 100C with the profit of 11C

Sold goods = 40C with the profit of 5C

= 40C *(1/20) = 2C

Remaining goods = 100C-40C= 60C

remaining goods sold profit is 11C - 2C = 9C

=(9C/60C)*100

= 15%

5. A person invested 40% of his money at 5% per annum. At what rate of interest should he invest the rest of his money to earn an overall interest of 11% per annum?

A.15%

B.20%

C.25%

D.30%

Explanation:

Here,

→  40% of the money invested at 5% profit

→ 11% is overall Profit

→ 6% is the difference between invested profit and overall Profit

→ Investment Ratio is 40% : 60% = 4% : 6%

→ Remaining Profit is 4% + 11% =15%

6. A person invested Rs.11000 in two investment schemes - one offering 7% p.a and another offering 12.5% p.a. How much should he be investing at 12.5% in order to get an overall return of 9.5%p.a?

A. One part is 5500 and Second part is 5500

B. One part is 8000 and Second part is 3000

C. One part is 7000 and Second part is 4000

D. One part is 6000 and Second part is 5000

Explanation:

One offering 7%p.a

Difference between 7% and 9.5% =2.5

= 2.5 *2 = 5

amount =5000

another offering 12.5%p.a

Difference between 12.5% and 9.5% =3

= 3*2 = 6

amount =6000

So, 1.6000 is invested for 7%p.a

2. 5000 is invested for 12.5%p.a

Total amount = 6000+5000= Rs.11,000

Dealing with the multiple objects

7. A person sold a Sofa and Chair at 10% profit and 10% loss respectively to get an overall profit of 6%. If the Sofa was sold for Rs.700 more than the Chair, what is the selling price of the Chair?

A.180

B.800

C.880

D.700

Explanation:

Overall profit 6%

Profit 10% = 10-6 = 4

loss 10% = -10-6 = 16 (In alligation we don't consider Negative signs)

Ratio of cost= 4: 1

CP = 400x : 100x

profit and loss = 40x   :-10x

total = 440x : 90x

Difference = 440x-90x= 350x

=> 350x=700

=>x=2

Sofa cost is 880, and Chair cost is 180

There fore 880-180 = 700

Dilution- Finding Concentration (in Ratios)

1. 8 liters of water is added to 24 liters of a solution containing milk and water in the ratio 3: 1. What is the ratio of milk to water in the resulting solution?

A. 18: 14

B. 12: 10

C. 16: 17

D. 20: 23

Explanation:

It can be solved in two ways:

Method 1:

the ratio of milk and water  = 3:1

Volume of milk and water (in the same order) = 18L, 6L ( the value 6 is 1/4th of 24 liters. So, 3*6=18 & 1*6=6)

8 liters of water is added then it becomes, 6+8= 14

Now the ratio of Milk and water = 18: 14 or 9: 7

Method 2:

The initial volume of solution, V1=24,

The final volume of solution, V2 =24+8=32

Now, V2/V1 = 32/24 = 4/3

This means when we multiply the initial solution with 4/3, we get the final solution. The concentration is inversely proportional to volume so it should be 3/4.

The equation becomes like this - Final concentration = Cinint* (3/4)   (→ V and C are inversely proportional to each other)

Cint = 3/4 (in total concentration 3/4 parts of milk - we take milk ratio as this time water is added to the solution)

Final Concentration Ratio for Milk =(3/4) * (3/4) = 9/16 (The 9/16 ratio means: if the total volume of solution 16L, then milk comprises 9L then the remaining 7L is water)

Hence Ratio of milk to water is 9: 7 or 18: 14.

2. 8 liters of milk is added to 32 liters of a solution containing milk and water in the ratio 3: 1. What is the ratio of milk to water in the resulting solution?

A. 1: 5

B. 3: 7

C. 4: 1

D. 5: 8

Explanation:

It can be solved in two ways:

Method 1:

the ratio of milk and water  = 3:1

milk and water in liters = 24, 8 (  the value 8 comes from 1/4th of 32 liters. So, 3*8=24, 1*8=8)

8 liters of milk is added then 24+8= 32

Now the ratio of Milk and water = 32: 8 = 4:1

Method 2:

The initial volume of solution, V1=32,

The final volume of solution, V2 =32+8=40

Now, V2/V1 = 40/32 = 5/4

This means when we multiply the initial solution volume with 5/4, we get the final solution volume. The concentration is inversely proportional to volume so it should be 4/5.

The equation becomes like this - Final concentration = Cint* (4/5)   (→ V and C are inversely proportional to each other)

Cint of water = 1/4 (in total concentration 1/4 parts is water - we take water ratio as this time milk is added to the solution)

Final Concentration Ratio for water =(4/5) * (1/4) = 1/5 (The 1/5 ratio means: if the total volume of solution 5L, then water comprises 1L then the remaining 4L is milk)

Hence Ratio of milk to water is 4:1.

Dilution- Finding Quantity to be added

3. How many liters of water needs to be added to 30 liters of milk with 90% concentration to make a solution containing 85% milk?

A. 2.5

B. 1.76

C. 4

D. 3

Explanation:

Cinitial = 90%, Cfinal = 85%

Cfinal/Cinitial = 85/90 = 17/18

As Concentration is inversely proportional to volume so,

vfinal/vinitial = 18/17 = (1+1/17) (we can write 18/17 as (1+1/17))

vfinal = 30 x (1+1/17)

= 30 + (30/17) = 30 + 1.76

Where 1.76 liters is the amount of water needed.

Replacement- Finding Final concentration

4. Ten liters of water is added to 40 liters of a mixture containing 70% milk. What is the concentration of the resulting mixture?

A. 18: 21

B. 13: 16

C. 17:15

D. 14:11

Explanation:

Given: Vinitial=40, Vfinal= 40+10= 50, Cinitial = 70%, Cfinal= ?

Vfinal/Vinitial= 50/40 = 5/4

Cfinal/Cinitial = 4/5

Cfinal= Cinitial x (4/5)

=  70% x (4/5)

= 56% ( it implies that out of 100 parts of the solution 56 parts is milk and the remaining 44 parts is water)

So, the ratio = 56:44 = 14: 11

Finding Final concentration

5. Ten liters of water is added to 40 liters of a mixture containing 70% milk. What is the concentration of the resulting mixture?

A. 76: 24

B. 74:26

C. 20: 80

D. 60:40

Explanation:

Given: Vinitial=40, Vfinal= 40+10= 50, Cinitial= 100%-70% = 30%, Cfinal= ?

Vfinal/Vinitial= 50/40 = 5/4

Cfinal/Cinitial = 4/5

Cfinal= Cinitial x (4/5)

=  30% x (4/5)

= 24% ( it implies that out of 100 parts of the solution 24 parts is water and the remaining 76 parts is milk)

So, the ratio = 76:24

Replacement- Finding the quantity

6. A cask contains 72 liters of a solution containing 90% milk. How many liters of the solution needs to be replaced with the water in order to decrease the concentration of the milk to 80%?

A. 5

B. 2.5

C. 8

D. 1/7

Explanation:

Two steps 1: removing stuff( removing some part of the solution)

initial concentration milk, C1 = 90%    (milk is being multiplied with some fraction)

amount of milk in liters = 90% x 72

After removal of a fraction = {90% x 72} (1-f) = 80% x 72

90% x (1-f) = 80% ( canceling 72 on both the sides)

(1-f) = 80%/ 90%

(1-f) = 8/ 9

f = 1/9

Quantity of water added = (1/9)* 72 = 8 liters

Repeated Dilution- Find the concentration

7. A cask contains 80 liters of milk with 96% concentration. Every day a boy removes 20 liters of the solution from the cask replaces it with water. What is the ratio of milk to water in the cask after 3 days?

A. 30.5%

B. 40.5%

C. 50.5%

D. 60.5%

Explanation:

Fraction f = 20/80 =1/4

Initial Concentration, C0 = 96%

Concentration after Day 1, C1 = 96% x (1-f)

Concentration after Day 2, C2 = [96% x (1-f)] x (1-f) = 96% x (1-f)2

Concentration after Day 3, C3 = [ 96% x (1-f)2] x (1-f) =  96% x (1-f)3            (use => Cfinal= Cinitial * (1-f)n)

=96% x (1-(1/4))3

= 96% x (3/4)3

= (96 x 27)/64 = 40.5%

Repeated Dilution- Different Fractions

8. A cask contains 80 liters of milk with 96% concentration. On the first day, a boy removes 20 liters of the solution from the cask and replaces with water. On the second day, he removes 16 liters and replaces with water. Finally, on the Third day, he removes 24 liters and replaces with water.  What is the ratio of milk to water in the cask after 3 days?

A. 425: 625

B. 504: 746

C. 200: 550

D. 325: 525

Explanation:

Cfinal= 96% x [(1-(20/80)) x (1-(16/80)) x (1- (24/80))]

= (24/25) x (3/4) x (4/5) x (7/10)

= (504/1250) (where the total amount of the solution is 1250 out of which the amount of milk is 504 and the amount of water is 746)

Ratio = 504: 746

Repeated replacement

9.  A cask contains 80 liters of a solution containing milk and water in the ratio 3: 1. Each day, a boy takes out 'x' liters of the solution and replaces it with water. After two days, the ratio of milk to water became 12: 13. Find x?

A. 20 liters

B. 26 liters

C. 36 liters

D. 16 liters

Explanation:

Cinitial = 3/4 x (milk ratio)

Cfinal = 12/25

Cfinal = Cinitial x (1-(x/80)) x (1-(x/80))

12/25 = 3/4 x (1-(x/80)) x (1-(x/80))

(12 x 4) /(3 x 25) = (1-(x/80))2

16/25 = (1-(x/80))2

(4/5)2 = (1-(x/80))2

(4/5) = 1-(x/80)

x/80 = 1- (4/5) = 1/5

x= 80/5 = 16 liters

a)17. 5

b) 18.5

c) 20

d) 133

Explanation:

Let the number be X.

Then, 4/17 of 17/19 of the number is (4/17) * (17/19) * X = (4/19) * X

3/38 of the number= (3/38) * X

Given:

the difference between these two values is 17.5.

Hence, [(4/19) * X - (3/38) * X ]= 17.5

Solving the equation, we have X=133

Therefore, the number is 133.

Let the four numbers be a, a+b, a+2b, and a+3b

Mean of the four numbers = (a+a+b+a+2b+a+3b)/4 = (4a+6b)/4 = 20

Substituting b as 6, we get the value of a= 11

The product of the first and the last number is 11× 29 which is equal to 319.
