Correct Answer: (4)
Solution: (4)
According to the question,
$15 \times 8$ men $\equiv 18 \times 10$ women
$\Rightarrow 2$ men $\equiv 3$ women
$\therefore 6$ men +6 women $\equiv(6+4)$ men $=10$ men
$\therefore M_{1} D_{1}=M_{2} D_{2}$
$\Rightarrow 15 \times 8=10 \times D_{2}$
$\Rightarrow D_{2}=12$ days
or additional men $=0$
