Answer:
60days
Step-by-step explanation:
A works 3/4 in 15 days
therefore, A = 3/4=15
so, A= 15x4÷3 = 20 days
B works 1÷8 in 5 days
therefore, B = 1/8=5
so, B = 5x8= 40 days
Total days =40+20=60 days

A can do of work in 15 days
A can do complete work in
Thus, A's 1 day work
B can do of work in 5 days
B can do complete work in
Thus, B's 1 day work
Total work is LCM of 20 and 40
A can do parts of work in 1 day
B can do parts of work in 1 day
