Question

A,b ,c can do some work in 36 days. A and b together do twice as much work as c alone, and a and c together can do thrice as much work as b alone. Find the time taken by c to do whole work?

Answer 1

1 day work for (A+B+C) = 1/36 ............(ii)

Now, (A+B) = 2C ..........................(i)

From (i)and(ii): 3C = 1/36

C = 1/108

Thus, C takes 108 days to complete the whole work alone.

Answer 2

Answer:

108 is the answer. as a+b+c work 36 days and a+b = 2C hence c works 108 days
