1. 400
2. 600
3. 300
4. 800

Answer 1

Correct Answer - Option 2 : 600

Given:

Difference b/w three-fifth of a number and 20% of the number = 240

Calculation:

Let, the number = 100x

Three-fifth of the number = 100x × (3/5) = 60x

20% of the number = 100x × 20% = 20x

According to the question,

⇒ 60x ─ 20x = 240

⇒ 40x = 240

⇒ x = 6

∴ required number = 100x = 100 × 6 = 600
