1. 12
2. 13
3. 14
4. 15
5. 16

Answer 1

Correct Answer - Option 5 : 16

Given:

Number of days 12 men take to make 5 cycles = 10 days

Concept used:

(M₁ × D₁ × H₁)/W₁ = (M₂ × D₂ × H₂)/W₂

Calculation:

(12 × 10)/5 = (15 × D₂)/10

⇒ D₂ = (12 × 10 × 10)/(15 × 5) = 16 days

∴ The number of days in which 15 men can make 10 cycles is 16 days.
