Assuming your question is A can finish work on 10 days and B can finish in 15 days. How many days can both finish the same work?
Solution:-
A does x work in 10 days
A does a x/10 work in 1 day
B does x work in 15 days
B does x/15 work in 1 day
Both do (x/10) + (x/15) work in 1 day
= 25x/150 = x/6
Both do x work in 6x/x = 6 days.
Answer - 6 days
Solution:-
A does x work in 10 days
A does a x/10 work in 1 day
B does x work in 15 days
B does x/15 work in 1 day
Both do (x/10) + (x/15) work in 1 day
= 25x/150 = x/6
Both do x work in 6x/x = 6 days.
Answer - 6 days
