Question

Navjot can do a piece of work in $6$ days working $10$ hours per day. In how many days can he do the same work if he increases his working hours by $2$ hours per day?

Answer 1

Let us consider the Navjot needs

$6\times 10=60hrs$ to complete.

Therefore,

If he works $(10+2)=12$ hrs per day

Then,

$\frac{60}{12}=5days$
