After 15 days are over.
on 16th day = 80 soldiers and food for ( 60 - 15) = 45 days.
Now 20 more soldiers come and total = 100
so, 80 soldiers can consume food in 45 days
and 1 soldier can consume = 45 * 80
and 100 soldiers can consume in ( 45 * 80) / 100 = 36 days.
So 15 days are already over + 36 more days = 51 days. hope it help. .
