Question

A and b can complete a piece of work 20 days a effeciency fall down by 40% and thus the total work completed in 24 days

Answer 1

Answer:

This question is equivalent to saying A & B work together for 16 days completing 16/30 part of work.

Remaining 14/30 part of work is completed by B alone in 44 - 16 = 28 days.

=> B alone can complete work in 28 x 30/14 = 60 days.

No equations, no fuss.
