Time and Work basics ( part 1) shortcut

If A completed the work in 4 days and B completed the same work in 5 days. How many days will they take on working together?

Answer: Let total work is (lcm of 4 and 5) = 20

A's work in 1 day = 20/4 = 5

B's work in 1 day = 20/5 = 4

Total work in 1 day if they work together = 4+5 =9 and total work = 20.

Therfore, working together they will complete the work in 20/9 days.
