Answer» Let A finishes the work in x days in 1 DAY, work completed by A = 1/x In 16 days , work = 16/x work let B finishes the work in y days In 44 days work done by B = 44/y work so, 16/x + 44/y = 1 .........( i ) & 1/x + 1/y = 1/ 30 .......( ii ) eq. ( i ) - ( ii ) x 16 16/x + 44/y - 16/x - 16/y = 1 - 16/30 28/y = 14/30 y = 60 Time TAKEN by B alone = 60 days |
