Question

A can do a work in double the time than what B takes to do it and B can do the same work in double the time
than what C takes to do it. If A and B together can complete the work in 4 days, then in how many days can C
alone complete the same work?​

Answer 1

"C" alone can complete the work in 3 days

Step-by-step explanation:

Step 1 of 2

Given

C=x

B= 2x

A= 4x

If A+B = 4

Then Find C

Step 2 of 2

1/A+1/B = 1/4

1/4x+1/2x = 1/4

1+2/4=x/4

3/4 = x/4

x=3
