15 farmers finish in 20 days
10 farmers do 2/3 in 20 days
5 farmers do 1/3 in 20 days
in one day 15 farmers do 1/20 of the work
21 students finish in 20 days
14 students could do 2/3 the work in 20 days
7 students do 1/3 the work in 20 days
in one day 21 students do 1/20 of the work
in one day 7 students do 1/3x1/20 = 1/60 of the work
15 farmers and 21 students finish in 10 days
10 farmers and 14 students do 2/3 in 10 days
5 farmers do 1/3 in 10 days
15 farmers and 14 students finish in 10 days
if the 14 students only helped for 9 days
the 15 farmers would have to work a little more than 10 days to finish
after 9 days 9/10 of the work would be done by 14 students and 15 farmers
leaving 1/10 of the work to do by 15 farmers alone
in one day 15 farmers do 1/20 of the work
in two days 15 farmers do 1/10 of the work
the 15 farmers will have to work a total 11 days to finish if 14 students quit helping after 9 days
