Question

A and B together can complete a work in 4 days. A alone can finish the work in 12
days. In how many days B alone can finish the work?​

Answer 1

Answer:

A, B and C together can finish a work in 4 days. If A alone can finish the same work in 12 days and B in 18 days, in how many days can C alone finish the same work? In 4 days, A & B together do 4*(1/12 + 1/18) = 5/9 of the work . So, in 4 days C does (1 - 5/9) = 4/9 of the work .
