Q. |
A and B can complete a job in x times the time that C would take to complete it. B and C can complete it in x times the time that A would take to complete it. A and C can complete it in x times the time taken by B to complete it. Find x. |
|
A. 4 |
|
|
B. 1 / 4 |
|
|
C. 1 / 2 |
|
|
D. 2 |
This is possible when the efficiency of A, B, and C are equal i.e. 1:1:1.
Hence A+B will take 1/2 the time taken by C.
B+C will take 1/2 the time taken by A.
C+A will take 1/2 the time taken by B.
x= 1/2.
