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.
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.
