A number is increased by 35% and then decreased by 25% and again increased by 15%. What is the total increase/decrease percentage (rounded off to the nearest integer) in the number?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 16% increase.
Let the initial number be 100.
New number = 100 × 135/100 × 75/100 × 115/100
⇒ 135 × 3/4 × 23/20 = 116.43 ≈ 116
Required answer = [(116 - 100)/100] × 100 = 16%
