Question

To complete a work A takes 50% more time than B .If together they takes 18 days to complete the work ,then B takes the time to do the work in:​

Answer 1

Answer:

30 days.

Step-by-step explanation:

The ratio between their times is:

A:B = 150 % / 100% = 3:2

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

So, total work = (18 days *2+3) units

                       = (18*5) units

                       = 90 units.

Then, B completes work in:

= 90 units/3 units per day

= 30 days.

Hence,  the 30 days taken by B to complete work.
