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
