A number is decreased from 200 to 150. Find the decrease percentage.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 25%

The value is decreased from 200 to 150. Thus, we know:-

⇒ Oldvalue−NewValueOldValue{Old value - New Value}\over{Old Value} × 100

⇒ (200 - 150)/(200) × 100

⇒ 50/200 × 100

⇒ 25%
