Question

A can do a piece of work in 5 days and b can do it in 6 days. How long will it take if both work together?

Answer 1

Hey mate...here is ur ans..☺☺

A can do a piece of work = 5 days
Work done by A in one day = 1/5

B can do a piece of work = 6 days
Work done B in 1 day = 1/6

So work done by them together =

$= > \frac{1}{5 } + \frac{1}{6} \\ \\ = > \frac{6 + 5}{30} \\ \\ = > \frac{11}{30}$

So work done => 30/11

Hope it helps u..thanks...☺☺✌
