Work done by jerry in 1 day = x
work done by tom in 1 day = x/3
work done in 15 days by jerry = 15x
work done in 15 days by tom = 15x/3 = 5x
Total work done = 20x
days required by tom to do 20x work = 20x / x/3 = 60 days
work done by tom in 1 day = x/3
work done in 15 days by jerry = 15x
work done in 15 days by tom = 15x/3 = 5x
Total work done = 20x
days required by tom to do 20x work = 20x / x/3 = 60 days
