Open in App
Solution

We know that,

Number of hours Ravi required to do a piece of work =15 hours

Number of hours Raman required to do a piece of work =12 hours

Work done by Ravi in 1 hour =115

And, Work done by Raman in 1 hour =112

Now, work done by both ravi and raman together in 1 hour =115+112=960=320

They can do work together in 203 hours =623 hours =6 hours 40 minutes

[23×60 minutes=40 minutes ]
