Correct Answer: 2
Solution : We know that if the number of days decreases, the number of men required to finish a work will increase. $\text{Number of days}(x)∝\frac{1}{\text{Number of men}(y)}$ $\therefore$ $\frac{x{_1}}{x{_2}} = \frac{y{_2}}{y{_1}}$ Given: $x{_1} = 18$; $y{_1} = 4$ and $x{_2} = 12$ ⇒ $\frac{18}{12} = \frac{y{_2}}{4}$ $\therefore y{_2} = 6$ $\therefore$ Number of more men required = 6 – 4 = 2 Hence, the correct answer is 2.
