Here are the solutions to the above questions of Percentage asked in the SSC exam by TCS. Some questions have alternate solutions.

Sol 1. (c)

According to the question

Sol 2. (c)

Income: Expenditure  Savings

     60 :        50       →         10

After increase in Income and Expenditure.

     96 :          85       →       11

Therefore, Net Increase in Savings = 100=10%

Sol 3. (d)

25% = 1/4

A : B = 5 : 4

65% = 13/20

C : A+B = 7 : 20

Balancing the ratio for A + B

A = 100, B = 80 and C = 63

Required % age =100 = 37

Sol 4. (c)

50% = 12

A:B = 3:2

Let income of A = 300 unit and B = 200 unit

Total = 300+200 = 500 unit

Increased income of A =300/140  x100= 420

Increased income of B = 200/190  x100= 380

Total income of A and B = 420+380 = 800

Required % =  800-500/500  x100= 60%

Sol 5.  (c) 20% = 1/5

Let the original price = 50 unit

⇒decreased price = 40 unit

Let the original sale = 100 unit

⇒New sale = (100+x) unit

Initial  revenue = 50 x 100 units

⇒Increased revenue = 40 × (100+x) units

According to the question 

(50 x 100) x160/100=  40 × (100+x)

⇒200 = 100 + x

⇒x = 100

Sol 6. (b)

20% = 1/5 , 30% = 3/10 and 25% = 1/4

⇒A:B = 4:5 and C:D = 13 : 10 and A:D = 4 : 3

Balancing the ratio for A and D

A:B:C:D = 40:50:39:30

Let

B = 50 unit and C = 39 unit

Now, 50 × 78/100= 39

⇒C is 0.78 of B .  (100+x)

Sol 7. (a)

We know that,

Price x Consumption = Expenditure

20% = 1/5and 8% = 2/25

                                        Initial : New

Price                                   5     :     6 

Expenditure                       25   :    27      

   _______________

Consumption                 25/5   : 27/6 

                                         10   :   9

%age decrease in consumption = 10-9/10  x 100 = 10% ans

Alternate :

Direct Trick

Sol 8. (a)

85% = 17/20

Let the original number = 20

According to the question 

75 + 17 unit = 20 unit

1 unit = 25

Original number (20 unit) = 25 x 20 = 500

Sol 9. (b)

20% = 1/5and 40% = 2/5

Let the amount at the end of 2nd, third and 4th years be a,b and c respectively.

a : b : c

              5 : 6

                    5 : 6

Balancing the ratio for b

a:b:c = 25 : 30 : 36

According to the question

(36-30) unit = 259.20

1 unit = 43.20

Amount at the end of 2nd year (25 unit) = 43.20 x 25

40% of this amount = 43.20 x 25 x  2/5= 432

Sol 10. (d)

Let the income of sudha = A 

According to the question

A ×12/100 × 80/100= 4800

A = 50,000

27% of A = 50,000 × 27/100= 13500

Sol 11.(b)            

                     Initial : New

30%increase   10  :   13

25% decrease   4  :    3

25% increase    4  :    5                                 

                             ________

                                          160  :   195

Desired percentage = 195-160/160  ×  100 = 21.87 ≈22%

Sol 12.(a)

                  A : A+B

                  55 :  100

                   11 :  20

Let A+B = 20 unit and A = 11 unit

B = 20-11 = 9 unit

According to the question

(11-9) unit = 8

1 unit = 4

Marks obtained by A (11 unit) = 11 x 4 = 44

Marks obtained by B (9 unit) = 9 x 4 = 36

Sol 13. (d)

Let the salaries of A and B are a and b respectively.

According to the question

a ×5/100= b × 20/100

a/b= 4/1

(4+1) unit = 43000

1 unit = 8600

A’s salary (4 unit) = 8600 x 4 = 34400

Sol 14. (a)

Sol 15. (c) 

Let x is the desired percentage 

124 ×  X/100= 49.60

x = 49.60/124 × 100 = 40  

Sol 16. (d)

Fractional value of 24% = 6/25

Therefore, A    : B

                 31   : 25

Desired percentage  = 31-25/31 x 100 = 600/31 %

Sol 17. (a) 

Venn diagram for the failed students:

Total failed students = 20+32+24 = 76%

Therefore, Students passed in both subjects = (100-76)% = 24%

Sol 18. (a)

Drawing a venn diagram:

Percentage passed in both subjects = 100 - (11+42+9) = 100 - 62 = 38%

Sol19. (c)

Let the population at the beginning of first year be x.

ATQ, =5512248

Therefore, x = 5468500

Sol 20. (a)

Let A = 50, then B = 50 × 20/100= 10

20% of B = 10 × 20/100= 2

2/50 × 100 = 4%

Clearly, 2 is 4% of A.

Sol 21. (a)

Total commission = 200000 × 2/100+ 200000 × 1.5/100+168000 ×  1/100= 8680

Sol 22. (c) 

Required percentage = 2.4100= 240

Sol 23. (a) 

%age score of mathematics = 84/90 × 100= 93.33 %

%age score of science = 45/50 × 100= 90 %

%age score of computer science = 23/25 × 100= 92 %

%age score of English = 68/80  × 100= 85 %
