Percentage questions with solutions
If 25% of a number is 50, what is 75% of the same number?
- (A)150
- (B)50
- (C)160
- (D)37.5
Show answer and explanation
Correct answer: (A) 150
25% of the number is 50, so the number is 50 × 100 ÷ 25 = 200. Now 75% of 200 = 200 × 75 ÷ 100 = 150. Hence the required value is 150.
Shortcut: Scale directly: 50 × 75/25 = 150.
The price of an item is first increased by 10% and then decreased by 40%. What is the net percentage change in the price?
- (A)34% decrease
- (B)26% decrease
- (C)30% decrease
- (D)34% increase
Show answer and explanation
Correct answer: (A) 34% decrease
Let the original price be 100. After a 10% increase it becomes 110. A 40% decrease on 110 gives 110 × 60 ÷ 100 = 66. The net change is 66 − 100 = -34, i.e. 34% decrease.
Shortcut: Net % change = a − b − ab/100 = 10 − 40 − 4 = -34%.
The price of an item is first increased by 20% and then decreased by 20%. What is the net percentage change in the price?
- (A)4% increase
- (B)4% decrease
- (C)1% increase
- (D)No change
Show answer and explanation
Correct answer: (B) 4% decrease
Let the original price be 100. After a 20% increase it becomes 120. A 20% decrease on 120 gives 120 × 80 ÷ 100 = 96. The net change is 96 − 100 = -4, i.e. 4% decrease.
Shortcut: Net % change = a − b − ab/100 = 20 − 20 − 4 = -4%.
If 25% of a number is 450, what is 60% of the same number?
- (A)1080
- (B)990
- (C)450
- (D)1170
Show answer and explanation
Correct answer: (A) 1080
25% of the number is 450, so the number is 450 × 100 ÷ 25 = 1800. Now 60% of 1800 = 1800 × 60 ÷ 100 = 1080. Hence the required value is 1080.
Shortcut: Scale directly: 450 × 60/25 = 1080.
The price of an item is first increased by 50% and then decreased by 20%. What is the net percentage change in the price?
- (A)20% increase
- (B)30% increase
- (C)40% increase
- (D)20% decrease
Show answer and explanation
Correct answer: (A) 20% increase
Let the original price be 100. After a 50% increase it becomes 150. A 20% decrease on 150 gives 150 × 80 ÷ 100 = 120. The net change is 120 − 100 = 20, i.e. 20% increase.
Shortcut: Net % change = a − b − ab/100 = 50 − 20 − 10 = 20%.
If 40% of a number is 120, what is 75% of the same number?
- (A)210
- (B)225
- (C)90
- (D)120
Show answer and explanation
Correct answer: (B) 225
40% of the number is 120, so the number is 120 × 100 ÷ 40 = 300. Now 75% of 300 = 300 × 75 ÷ 100 = 225. Hence the required value is 225.
Shortcut: Scale directly: 120 × 75/40 = 225.
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 50% of a number is 700, what is 30% of the same number?
- (A)490
- (B)210
- (C)350
- (D)420
Show answer and explanation
Correct answer: (D) 420
50% of the number is 700, so the number is 700 × 100 ÷ 50 = 1400. Now 30% of 1400 = 1400 × 30 ÷ 100 = 420. Hence the required value is 420.
Shortcut: Scale directly: 700 × 30/50 = 420.
If 50% of a number is 700, what is 75% of the same number?
- (A)700
- (B)980
- (C)525
- (D)1050
Show answer and explanation
Correct answer: (D) 1050
50% of the number is 700, so the number is 700 × 100 ÷ 50 = 1400. Now 75% of 1400 = 1400 × 75 ÷ 100 = 1050. Hence the required value is 1050.
Shortcut: Scale directly: 700 × 75/50 = 1050.
