Answer» Correct Answer - Option 4 : 60 days Given: 3 men, 4 women, and 5 boys can complete work in 47 days Calculation: 3 men, 4 women, and 5 boys can complete work in 47 days \( \Rightarrow \frac{{47}}{{\frac{1}{3}\; + \;\frac{1}{4}\; + \;\frac{1}{5}\;}}\) \( \Rightarrow \frac{{47}}{{\frac{{20 + 15 + 12}}{{60}}\;}}\) ⇒ (47/47) × 60 ⇒ 60 days |
