Answer 1

Answer:

A, b and c were employed to complete a work. Initially all of them worked together, then a left the work and the remaining work is completed by b and c together. 70% of the work is completed by b and c working together and total work is completed in 13 days. Also, a worked with b and c for the initial 3 days and then a left the work. If c is 1/3rd more efficient than b then find the time taken to complete the work when, only a and b work together.
