Answer:
Let a man can do 1 unit / day.
Total work = 40 men ×40 days
= 1600 units
40 men can do the work in 10 days
= 400 units
According to question,
{ 5 men left after to days }
35 men can do the work in 10 days
= 350 units
30 men can do the work in 10 days
= 300
25 men can do the work in 10 days
= 250
20 men can do the work in 10 days
=200
men left 20 - 5 = 15 and
work left = 1600-1500 = 100 unit
They will complete in 100/15 = 6 2/3 days
Total days = 50 + 6 2/3 = 56 2/3 days.
Hope it's Help You ❇
