Solution

The correct option is C 5 days
According to the question,
Work done by 1 man = Work done by 2 women
8 men + 4 women
= (16 + 4) women = 20 women
4 men + 8 women = 16 women
20 women’s 2 days work
=26=13part
Remaining work =113=23
20 women complete 1 work in 6 days
16 women will do 23 work in 20×616×23=5 days
