Step-by-step explanation:
A man can do ‘M' units of work in 1 day.
8 men worked for 6 days,
Work done= Rate x Time
Work done = 8M x 6 =48 M
The same work is done by 12 men with the rate of 12M
Work done = Rate x Time
48M = 12M x Time
48 = 12 x Time
48/12 = Time
4 = Time
4 days
Ans: in 4 days 12 men can build the wall.
