Question

What A can do in 3 days, B can do in 4 days. If C takes 6 days to do a job that B can do in 5 days, how many days will it take A to do a job that C can do in 16 days?​

Answer 1

Well A=3 when B=4
So when B=5 then should A=4
If C=6 when B=5 then when C=6, A=4
So when C=16, A should equal 14
So I think the answer is 14
