A can complete a task in 18 days, but B can do the identical task in 15 days. B worked for ten days before quitting. How many days can A accomplish the remaining job on his own?
A. 5 B. 5 1/2 C. 6 D. 8
Explanation: B's ten-day work Equals ( 1/15 x 10) = 2/3.Work remaining = ( 1 - 2/3 ) = 1/3.A now completes 1/18 of the job in one day.As a result, A completes 1/3 of the task in ( 18 x 1/3 ) = 6 days.
