Answer 1

First,this question belongs to time-work relationship problems and it is really important for competitive ecaminations.
Try to understand the concept--
Doing work is an individual thing .
and learn this relationship----
Total work done==(working capacity of that individual)*(time taken by that individual to perform that amount of work).
So,here we go ,use this hasic formula in these types of problems.
