Question

A” finishes his work in 15 days while “B” takes 10 days. How many days will the same work be done if they work together?

Answer 1

If A takes 15 days to finish his work then,

A’s 1 day of work = 1/15


B’s 1 day of work = 1/10

Total work is done by A and B in 1 day = 1/15 + 1/10

If we use LCM(15, 10), we would get
1 day’s work of A and B =
