Correct Answer - Option 2 : 1875

**Given:**

Three-fourth of fifth-sixth of two-fifth of a number = 625

**Calculation:**

Let, the number = 100x

According to the question,

⇒ (3/4) × (5/6) × (2/5) × 100x = 625

⇒ 25x = 625

⇒ x = 25

∴ 100x = 100 × 25 = 2500

∴ 75% of 2500 = (75/100) × 2500 = 1875
