Question

To complete a work P takes 25% more time than Q. If together they take 25 days to complete the work, how
much time shall Q take to do it alone?​

Answer 1

Explanation:

Ratio of time

A : B

3 : 2

[AB=150%100%=32]

efficiency of work =2:3(Efficiency is always inversely proportion to time)

Total work = 18days×(2+3) unit

= 90 units

B completes the work in

=90units3units/day= 30 days

Answer 2

Answer: 267 hours.

Explanation:

25%+100%+100%=225%

225%= 25 days

25 days=25x24

             =600h

1%=600 divide 225

    =2.6666667

100%=2.666667x 100%

        = 266.66666667

        =267 hrs

I think. Please don't blame me if wrong.
