Percentage questions with solutions
If 25% of a number is 475, what is 75% of the same number?
- (A)1330
- (B)356.25
- (C)1520
- (D)1425
Show answer and explanation
Correct answer: (D) 1425
25% of the number is 475, so the number is 475 × 100 ÷ 25 = 1900. Now 75% of 1900 = 1900 × 75 ÷ 100 = 1425. Hence the required value is 1425.
Shortcut: Scale directly: 475 × 75/25 = 1425.
The price of an item is first increased by 50% and then decreased by 25%. What is the net percentage change in the price?
- (A)12.5% increase
- (B)37.5% increase
- (C)12.5% decrease
- (D)25% increase
Show answer and explanation
Correct answer: (A) 12.5% increase
Let the original price be 100. After a 50% increase it becomes 150. A 25% decrease on 150 gives 150 × 75 ÷ 100 = 112.5. The net change is 112.5 − 100 = 12.5, i.e. 12.5% increase.
Shortcut: Net % change = a − b − ab/100 = 50 − 25 − 12.5 = 12.5%.
If 40% of a number is 760, what is 60% of the same number?
- (A)1140
- (B)760
- (C)1235
- (D)456
Show answer and explanation
Correct answer: (A) 1140
40% of the number is 760, so the number is 760 × 100 ÷ 40 = 1900. Now 60% of 1900 = 1900 × 60 ÷ 100 = 1140. Hence the required value is 1140.
Shortcut: Scale directly: 760 × 60/40 = 1140.
The price of an item is first increased by 20% and then decreased by 10%. What is the net percentage change in the price?
- (A)8% increase
- (B)8% decrease
- (C)12% increase
- (D)10% increase
Show answer and explanation
Correct answer: (A) 8% increase
Let the original price be 100. After a 20% increase it becomes 120. A 10% decrease on 120 gives 120 × 90 ÷ 100 = 108. The net change is 108 − 100 = 8, i.e. 8% increase.
Shortcut: Net % change = a − b − ab/100 = 20 − 10 − 2 = 8%.
The price of an item is first increased by 50% and then decreased by 30%. What is the net percentage change in the price?
- (A)5% increase
- (B)5% decrease
- (C)20% increase
- (D)35% increase
Show answer and explanation
Correct answer: (A) 5% increase
Let the original price be 100. After a 50% increase it becomes 150. A 30% decrease on 150 gives 150 × 70 ÷ 100 = 105. The net change is 105 − 100 = 5, i.e. 5% increase.
Shortcut: Net % change = a − b − ab/100 = 50 − 30 − 15 = 5%.
If 40% of a number is 800, what is 35% of the same number?
- (A)600
- (B)280
- (C)700
- (D)800
Show answer and explanation
Correct answer: (C) 700
40% of the number is 800, so the number is 800 × 100 ÷ 40 = 2000. Now 35% of 2000 = 2000 × 35 ÷ 100 = 700. Hence the required value is 700.
Shortcut: Scale directly: 800 × 35/40 = 700.
The price of an item is first increased by 30% and then decreased by 40%. What is the net percentage change in the price?
- (A)2% increase
- (B)10% decrease
- (C)22% increase
- (D)22% decrease
Show answer and explanation
Correct answer: (D) 22% decrease
Let the original price be 100. After a 30% increase it becomes 130. A 40% decrease on 130 gives 130 × 60 ÷ 100 = 78. The net change is 78 − 100 = -22, i.e. 22% decrease.
Shortcut: Net % change = a − b − ab/100 = 30 − 40 − 12 = -22%.
If 20% of a number is 40, what is 60% of the same number?
- (A)130
- (B)120
- (C)40
- (D)24
Show answer and explanation
Correct answer: (B) 120
20% of the number is 40, so the number is 40 × 100 ÷ 20 = 200. Now 60% of 200 = 200 × 60 ÷ 100 = 120. Hence the required value is 120.
Shortcut: Scale directly: 40 × 60/20 = 120.
