Here are the solutions to the above questions of Percentage asked by TCS in SSC CGL Tier 1.

Sol 1. (c)

According to the question 300-3x = 100 + x

X = 50

50% of 210 = 105

(50+20)% of 180 = 126

Required percentage Sol 2. (c)

Income : Expenditure Savings

60     :        50       →         10

After increase in Income and Expenditure.

96    :          85       →       11

Therefore, Net Increase in Savings = 1/10 × 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 Sol 4. (c)

50% = 1/2

A:B = 3:2

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

Total = 300+200 = 500 unit

Increased income of A =300× 140/100= 420

Increased income of B = 200× 190/100= 380

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

Required % =  800-500 /500  × 100= 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)× 160/100=  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 78100= 39

⇒ C is 0.78 of B .

Sol 7. (a)

We know that,

Price x Consumption = Expenditure

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

Initial : New

Price                                   5     :     6

_______________

10   :   9

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

Alternate :

Direct Trick Desired percentage = 12120x 100 = 10%

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. (a)

15% = 3/20

Let sudha’s income = 2000

⇒ Sudha’s saving = 300

⇒ Sudha’s expenditure = 2000-300 = 1700

Sudha’s increased saving = 300 x 160/100= 480

Sudha’s increased expenditure = 1700 x 120/100= 2040

Sudha’s increased income = 2040+480 = 2520

Desired percentage = 2520-2000/2000 × 100 = 26 %

Sol 10.(b)

20% = 1/5 and 25% = 1/4

A:B = 4:5 and C:D = 6 : 5 and A:D = 4 : 3

Balancing the ratio for A and D

A:B:C:D = 20:25:18:15

Let

B = 25 unit and C = 18 unit

Now, 25 × 72/100= 18

⇒ C is 0.72 of B .

Sol 11. (a)

75% = 3/4

Let the income of Surbhi = 400 unit

saving of Surbhi = 100 unit

So expenditure of Surbhi = 400-100 = 300 unit

Increased income of surbhi = 400× 220/100= 480 unit

Decreased saving of Surbhi = 100× 99/100= 99 unit

New expenditure of  surbhi = 480-99 = 381 unit

Desired %age =381-300/300 × 100 = 27 %

Sol 12. (a)

40% = 2/5

Let the income of B = 500

⇒ The income of A = 700

Total income of A and B = 1200

Increased income of A = 700 × 125/100= 875

Increased income of B = 500 × 140/100= 700

Total income of A and B = 875+700 = 1575
