Question

Rupesh and Sailesh can do a piece of work in 12 days where as Sailesh

alone can do the work in 16 days. In how many days can Rupesh alone do the

work?​

Answer 1

Answer:

Rupesh will do the work in 48 days.

Answer 2

Let sailesh work be A

and

rupesh work be B

(A+B)'s 1 day work = 1/12

"A" first day work = 1/16

"B" first day work = 1/12 - 1/ 16

1/12 * 4/4 - 1/16 * 3/3

4 - 3 /48 = 1/48= 48

Rupesh alone do the work in 48 days
