Answer Posted / h.m.mohsin pervaze
Ben takes 8 days to do 1 piece of work, So Ben
completes in one day = 1/8 portion of work
Joe is three times faster of Ben, So Joe
completes in one day = 3/8 portion of work
Ram is five times faster of Ben, So Joe
completes in one day = 5/8 portion of work
So, in one day their combined work result = 1/8+3/8+5/8
= 9/8 portions of work in 1 day.
So to finish 1 portion of work, they'll need = 1/9/8 = 8/9
Thus answer is they'll need 8/9 days to complete 1 piece of
work.
