Answer:
6 Days
Step-by-step explanation:
In 8 days, A can finish 1 work
so, in 1 day, A can finish 1/8 part of work
Again,
In 24 days, B can finish 1 work
so, in 1 day, B can finish 1/24 part of work
Therefore, in 1 day, A and B together can finish 1/8+1/24 part of work
=3+1/24 part of work
=4/24 part of work
=1/6 part of work
Now,
A and B together finish 1/6 part of work in 1 day
so, A and B together finish 1(whole) work in 1÷1/6 days
=1×6/1 days
=6 days [Answer]
