Manish takes 9 days more than his father to do a certain piece of work. Together they can do the work in 6 days. How many days will Manish take to do that work alone?

║⊕ANSWER⊕║

Let's assume the father does the work in 1 day then Manish will do that work in of course, 1+9 = 10 days.

One day work of father = 10

One day work of Manish = 1

Together they can do the work in 6 days.

Total work = (1+10)×6

                     = 66

Manish will take time to do the whole work alone = 66/1

                                                                                       = 66 days
