Correct Answer: 6 men

Explanation:

2 men and 5 women require 3 days to complete $\frac{1}{4}$ Job

They complete $\frac{1}{4\times 3}$ =$\frac{1}{12}$ job in 1 day

3 men + 5 women require 2 days to complete $\frac{1}{12}$ job

They complete $\frac{1}{4\times 3}$ = $\frac{1}{8}$ in 1 days

3men + 5 women = $\frac{1}{8}$

2 men + 5 women = $\frac{1}{12}$

(-) 1 man = $\frac{1}{24}$

$\frac{1}{24}$ job is done in 1 day by 1 men

1 job is done in 1 day by 24 men1 job is done in 4 day by $\frac{1}{24}$ = 6 men.
