If 3 men or 4 women can construct a wall in 43 days then in how many days 7 men and 5 women will construct it?

Given:


3 men or 4 women can construct a wall in 43 days.
3 men = 4 women.


4 women can construct the wall in 43 days.
So,
1 woman can build the wall in = 43 x 4 days.
Hence,
43/3 women can construct the wall = (43×4×3)/43 = 12 days.


Hence 12 days are needed to construct the wall by 7 men and 5 women.
