Answer:B
A takes twice as long as B or three times as long as C to complete a project. They can complete the task in two days if they work together. B is capable of completing the task on his own in the following areas:
A. 4 days B. 6 days C. 8 days D. 12 days
Explanation: Assume that A, B, and C accomplish the task in x, x/2, and x/3 days, respectively.Then, 1/x + 2/x + 3/x = 1/2.6/x = 1/2.x equals 12.As a result, B will accomplish the task in (12/2) = 6 days.
