Question

One-fifth of half of a number is 20. Then 20% of that number is:
1. 60
2. 40
3. 20
4. 80

Answer 1

Correct Answer - Option 2 : 40

Given:

One-fifth of half of a number is 20

Calculations:

Let the number is = x

According to the question,

⇒ 1/5 of 1/2 of x = 20

⇒ x = 20 × 5 × 2

⇒ x = 200

⇒ 20% of 200 = (20/100) × 200 = 40

∴ 20% of that number is 40
