Question

1. A takes 10 days less than the time taken by B to finish a piece of work. If both A and B
can finish the work in 12 days, find the time taken by B to finish the work.

Answer 1

Step-by-step explanation:

Let A can finish the work in x days

B can finish the work in x+10 days

So the work done by A in one day = 1/x times the total work

and the work done by B in one day = 1/x+10 times the total work

In 12 days, then can do the work together

(12/x)+(12/x+10)=1

solving the equation we get

x=20

Hence A complete the work in 20 days and B in 20+10 = 30 days

Answer 2

Answer:

B will complete his work in 14 day
