Answer:
6 days
Step-by-step explanation:
Assume, A does 1 unit of work in 15 days and B does 1 unit of work in 10 days.
taking LCM of 15 and 10 i.e 30, we can say that in 30 days A will complete 2 unit of work and B will complete 3 unit of work. So all in all 5 units of work will be covered by A and B both in 30 days if they work together. Hence for 1 unit of work they will take 30/5= 6 days.
