1. 75
2. 60
3. 21
4. 35

Answer 1

Correct Answer - Option 4 : 35

Given:

The product of three numbers = 10290

Their ratios = 3 : 5 : 2

Calculation:

Let the ratio of number be 3x, 5x and 2x respectively

Since,

⇒ (3x) × (5x) × (2x) = 10290

⇒ 30x³ = 10290

⇒ x³ = 10290/30

⇒ x3 = 343

⇒ x = 7

Now,

The greatest number among the three = 5x

⇒ 5 × 7

⇒ 35

∴ Required greater number is 35
