Let a man can do 1 unit/ day.
Total work = 40men×40days40men×40days
= 1600 units
40 men can do the work in 10 days
= 400 units
According to question,
(5men left after 10 days)
35 men can do the work in 10 days
=350 units
30 men can do tlhe 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 units
they will complete in 100/15=6 2/3
Total days =50+6 2/3=56 2/3 days
HOPE IT HELPS YOU !!
