Puzzle - Answer

At the bread factory, 2 bread-men can bake 6 rolls in 3 hours.

By this same reasoning, how many bread-men will it take to bake 22 rolls in 5 hours?

 [Ref: ZYWV] © Kevin Stone

Answer: Five bread-men.

2 bread-men can bake 6 rolls in 3 hours,
1 bread-man can bake 3 rolls in 3 hours,
1 bread-man can bake 5 rolls in 5 hours.

So 4 bread-men could only make 20 rolls in 5 hours, and we require the extra bread-man to do the remaining 2 rolls.
