Question

A takes four time as much time as B or thrice as much time as C to finish a piece of work. Working together,
they can finish the work in 3 days. B can do the work alone in:
10 days
6 days
8 days
12 days​

Answer 1

Answer:

6 is the correct answer

Step-by-step explanation:

Suppose A, B and C take x, x and x days respectively to finish the work.

2 3

Then, 1 + 2 + 3 = 1

x x x 2

6 = 1

x 2

x = 12.

So, B takes (12/2) = 6 days to finish the work.
