Discussion Board
P2

R can do a piece of work in 90 D.
Let TOTAL WORK = 90 units.

R-> 90 days = 1 unit/day
In 10 days, R has completed 10 units.

Remaining Work = 80 units.
S finishes this in 48 days.
So rate of work if B = 80 / 48 = 5 / 3 unit/day

R + S = 1+ 5/3 = 8 / 3
So, TIME TAKEN = 80 / 8*3 = 30 D
