Question

The difference between two numbers is 20 % of the larger number. If the smaller number is 20, then the largest number is:
1. 80
2. 50
3. 45
4. 25

Answer 1

Correct Answer - Option 4 : 25

Given:

Difference between two numbers = 20 % of the larger number

Smaller number = 20

Calculations:

Let the larger number be x

⇒ x – 20 = (20/100)x

⇒ x – 20 = (1/5)x

⇒ x – (1/5)x = 20

⇒ 4x/5 = 20

⇒ 4x = 100

⇒ x = 25

∴ The largest number is 25
