a and b complete 1/3 of the work in one day
in 2 days, they complete 2 x 1/3 = 2/3 of the work
the remaining fraction is 1/3
a takes 2 more days to complete the work
the rate at which a is working = (1/3) / 2 = 1/6 per day
In the first 2 days, a completed 1/6 x 2 = 1/3 of the work
b completed 2/3 - 1/3 = 1/3
the rate at which b is working = (1/3) / 2 = 1/6 per day
b alone could take 6 days to complete the work
in 2 days, they complete 2 x 1/3 = 2/3 of the work
the remaining fraction is 1/3
a takes 2 more days to complete the work
the rate at which a is working = (1/3) / 2 = 1/6 per day
In the first 2 days, a completed 1/6 x 2 = 1/3 of the work
b completed 2/3 - 1/3 = 1/3
the rate at which b is working = (1/3) / 2 = 1/6 per day
