Question

Kamran can finish a job alone in 7.5hours and Munir can finish the same work alone in 5hours ,if they work together , in how much time can they finish the work ?

Answer 1

Hello!

Kamaran can finish in 7.5 hrs

So work done in 1 hour is 2/15

Munir can finish in 5 hrs

So work done in 1 hour is 3/15

Work done together in an hour  is 2+3/15 = 5/15 = 1/3

So work will be done in 3hrs

Hope it helps.
