Best answer
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.
