explain krna plz

Answer 1

Probably in 11 days.
It make something like a patter. The manpower is 6 and 10=16 and they finish the work in 15 days. When you subtract 15-16, you get -1. The man power in the second case is 7+5=12. Therefore we will add he value obtained by subtracting the time in days and there manpower in the first case. So we will get 12-1=11. Therefore hey will take 11 days
