Answer:
6 days
Step-by-step explanation:
If 4 men can do a job in 20 days, it means 1 man does 1/80th of the work in a day.
If 6 boys can do a job in 20 days, it means 1 boy does 1/120th of the work in a day.
So 6 men will do 6/80th of the work in a day, and 11 boys will do 11/120th of the work in a day. Together, the 6 men and 11 boys will do (6/80) +(11/120) or (9/120) + (11/120) = 20/120th of the work in a day.
So they will complete the work in 120/20 = 6 days.
