Question

The number of days taken by Q to do a piece of work is 16 days more than that by P.After 6 days of working together they found that three fifth of the work was remaining .In how many days P alone can do complete the whole work?​

Answer 1

Answer:

24

Step-by-step explanation:

P + Q complete 2/5th of work in 6 days, so the whole work will be completed in 15 days. [ 2/5th - 6 days

                   1 work -  {6/ (2/5) } * 1 = 15 ]

ATQ, 1/P + 1/(P+16) = 1/15

          => p = 24 days
