Percentage questions with solutions

Q1.PercentageEasy

If 40% of a number is 280, what is 35% of the same number?

  1. (A)280
  2. (B)98
  3. (C)210
  4. (D)245
Show answer and explanation

Correct answer: (D) 245

40% of the number is 280, so the number is 280 × 100 ÷ 40 = 700. Now 35% of 700 = 700 × 35 ÷ 100 = 245. Hence the required value is 245.

Shortcut: Scale directly: 280 × 35/40 = 245.

Q3.PercentageModerate

The price of an item is first increased by 25% and then decreased by 40%. What is the net percentage change in the price?

  1. (A)15% decrease
  2. (B)25% increase
  3. (C)25% decrease
  4. (D)5% decrease
Show answer and explanation

Correct answer: (C) 25% decrease

Let the original price be 100. After a 25% increase it becomes 125. A 40% decrease on 125 gives 125 × 60 ÷ 100 = 75. The net change is 75 − 100 = -25, i.e. 25% decrease.

Shortcut: Net % change = a − b − ab/100 = 25 − 40 − 10 = -25%.
