Question

to complete the work a takes 50% more time than b if together they take 18 days to complete the work how much time shall b take to do it​

Answer 1

Answer:

45 days

Step-by-step explanation:

Let A do the work in x days.

Then the work done by A in one day is 1/x.

Since B takes 50% more time, B will do the work in x + 50/100 x

= 3x/2

The work done by B in one day is 2/3x

1/x + 2/3x = 1/18

5/3x = 1/18

3x = 18×5

x = 6×5

x = 30

So A takes 30 days to complete the task.

B takes 3x/2 days, which is 3×30/2 = 45 days
