Answer:
4.5 Days
Step-by-step explanation:
1st one & 2nd one can complete a work in 24 days and 36 days respectively
1st son 1 day work = 1/24
2nd son 1 day work = 1/36
man could alone complete the whole work in 36/11 days
=> Man 1 Day work = 11/36
The man can do double work in same time
=> 3rd son 1 Day work = 11/72
All three son 1 day work = 1/24 + 1/36 + 11/72
= (3 + 2 + 11)/72
= 16/72
= 2/9
all his sons together can complete the work in 9/2 Days
= 4.5 Days
