If 8 men and 2 boys working together, can do seven times as much work per hour as a man and a boy together. Find the ratio of the work done by a man and that of a boy for a given time? Pick one:
A) 1:5	B) 2:3	C) 3:8	D) 5:1	E) 5:2
8M + 2B = 7(1M + 1B)   8M + 2B = 7M + 7B   1M = 5B   The required ratio of work done by a man and a boy = 5:1   Answer:5:1
