Question

A and B together can do a piece of work in 6⅔
days, but B alone can do it in 10 days. How
long will A take to do it alone ?​

Answer 1

Answer:

As time value can't be taken in negative to complete a work. So 'A' alone will take 24 days time and 'B' alone will take 24+6= 30 days time to complete 'W' work. A, B, and C together can do a piece of work in 15 days. B alone can do it in 30 days and C alone can do it in 40 days.
