Answer» Correct Answer - Option 3 : 18 days Given: 48 Persons make a bridge in 15 days working 6 hours a day. Concept Used: M1 × H1 × D1 = M2 × H2 × D2 Where, M = No of persons H = Hours of working in a day D = No of days to complete the work Calculation: M1 × H1 × D1 = M2 × H2 × D2 ⇒ 48 × 15 × 6 = 30 × 8 × D2 ⇒ D2 = 18 days ∴ 30 men working 8 hours a day can complete in 18 days. |
