Question

A can complete a work in 12 days and B can complete the same work in 24 days. Find the time taken by both A and B together to complete the work.

RRB Paper · Accepted Answer

Time taken = (1 / Rate of work of A) + (1 / Rate of work of B)

Putting the values given in the question, we get:

Time taken = (1 / 12 days) + (1 / 24 days)

Time taken = 1/8

So it would take A and B a total of 8 days to complete the work together.
