Answer 1

required answer

________________

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.
