Correct Answer: (1)
Solution: (1)
Work done by 14 men in 3 days days $=\frac{3}{18}=\frac{1}{6}$
Work done by 10 women in 3 days $=W_{1}$
$\therefore M_{1} D_{1}=M_{2} D_{2}$
$\Rightarrow 15 \times 24=\frac{10 \times 3}{W_{1}}$
$\Rightarrow W_{1}=\frac{10 \times 3}{15 \times 24}=\frac{1}{12}$
$\therefore$ Total work done $=\frac{1}{6}+\frac{1}{12}=\frac{2+1}{12}=\frac{1}{4}$
$\therefore$ Remaining work $=1-\frac{1}{4}=\frac{3}{4}$
