Question

If 25 men can do a work in 15 days, then in how many days 15 men can do the same work?
1. 36 days
2. 25 days
3. 31 days
4. 32 days

Answer 1

Correct Answer - Option 2 : 25 days

Given:

M₁ = 25

D₁ = 15

M₂ = 15

Formula Used:

(M₁ × D₁) = (M₂ × D₂)

Where M1 → Initial Men

D1 → Initial day

M2 → Final men

D2 → Final day

Calculation:

(M₁ × D₁) = (M₂ × D₂)

⇒ 25 × 15 = 15 × D₂

⇒ D₂ = 25

∴ The time taken by 15 men to do the same work is 25 days.
