Question

A works twice as fast as B. If both of them can together finish a piece of work in 12 days,then B alone can do it in how many days? ​

Answer 1

Answer:

12 days

Step-by-step explanation:

Let completes in x days.

B completes twice as A then B works in 2x

1/A+1/B=1/8

1/X+1/2X=1/8

Taking LCM

2/2X+1/2X=1/8

3/2X=1/8

2X/3=8

2X=24

X=12

So,B can do work in 12+12=24 days
