navin can do a piece of work in 8 days working 9 hours per day . in how many days can he do the same work if he increases his working hours by 3

5 days

Step-by-step explanation:

nitially he is working 10 Hrs and is been able to complete his work on 6th day

Now if we are including 6th day means he is working 6*10=60 hrs

and by increasing 2 hrs he is now working 12 hrs a day

our work requirement is 60 hrs

60/12=5 days

By the end of 5th day he will manage to complete his work if his efficiency is constant
