1. 2000
2. 15000
3. 10,000
4. 1500

Answer 1

Correct Answer - Option 3 : 10,000

Given

75% of a number is added to 2500

Calculation

let the number is x.

75% of x + 2500 = x

⇒ 2500 = x - 75% of x

⇒ 2500 = (100x - 75x)/100

⇒ 2500 = 25x/100

⇒ (2500 × 100)/25 = x

⇒ 10,000 = x

∴ The number is 10,000.
