The number of days required by 4 men and 4 women to finish the work is 12 days.

Step-by-step explanation:

Since we have given that

8 men or 12 women can do a piece of work = 10 days

Number of days for 4 men and 4 women is given by

$\dfrac{10}{\dfrac{4}{8}+\dfrac{4}{12}}\\\\=\dfrac{10}{\dfrac{1}{2}+\dfrac{1}{3}}\\\\=\dfrac{10}{\dfrac{3+2}{6}}\\\\=\dfrac{10}{\dfrac{5}{6}}\\\\=\dfrac{10\times 6}{5}\\\\=2\times 6\\\\=12\ days$

Hence, the number of days required by 4 men and 4 women to finish the work is 12 days.
