Answer 1

Answer:

A+B, one work= 6 days

A alone = 10 days

So,

Work done by A in 1 day = (1/10)th of the total work.

In 6 days, work done by A = (6/10)th of the total work.

So, work done by B in 6 days = {1-(6/10)}= (4/10)

Work done by B in 1 day = (4/10)*(1/6) = (1/15)th of total work.

So Total work can be done by B in 15 days.
