Answer» Correct Answer - Option 4 : 10 days Given: M1 = 12 D1 = 15 M2 = 18 Formula Used: (M1 × D1) = (M2 × D2) Where M1 → Initial Men D1 → Initial day M2 → Final men D2 → Final day Calculation: (M1 × D1) = (M2 × D2) ⇒ 12 × 15 = 18 × D2 ⇒ D2 = 10 ∴ The time taken by 18 men to do the same work is 10 days. |
