Answer» Correct Answer - Option 1 : B Given: 5 men can do work in 9 days Concept used: If n person can do work in x days, then 1 person can do the work in (n × x) days. Calculation: 5 men can do work in 9 days ⇒ 1 man can do the same work in 9 × 5 = 45 days 3 men can do the same work in 45/3 days ∴ 3 men can do the work in 15 days |
