Correct Answer: 15 days
Solution :
According to the question,
3 men = 5 women
1 man = $\frac{5}{3}$ women
9 men = $9 \times \frac{5}{3}$ women = 15 women
Now the total work is done by = 15 women and 4 women = 19 women
Let the total work be completed by 19 women in $x$ days.
We know that 5 women can complete the work in 57 days.
$M_1D_1= M_2D_2$
Where $M_1$ and $M_2$ are women and $D1$ and $D_2$ are days.
$⇒5 \times 57= 19 \times x$
$⇒x = \frac{5 \times 57}{19} = 15$ days.
Hence, the correct answer is 15 days.
