Answer» Correct Answer - Option 1 : 36 Given: M1 = 12 D1 = 10 H1 = 8 W1 = 1 M2 = 16 H2 = 5 W2 = 3 Formula Used: (M1 × D1 × H1)/W1 = (M2 × D2 × H2)/W2 Where M1 → Initial Men D1 → Initial day H1 → Initial hour M2 → Final men D2 → Final day H2 → Final hour Calculation: (M1 × D1 × H1)/W1 = (M2 × D2 × H2)/W2 ⇒ (12 × 10 × 8)/1 = (16 × D2 × 5)/(3) ⇒ (12 × 10 × 8 × 3 ) = (16 × 5 × D2) ⇒ D2 = 2880/80 ⇒ D2 = 36 days ∴ The time taken by 16 men to do 3 times thework while working 5 hours per day is 7 days. |
