Assuming they can work in parallel, the answer should be 5. 5 men produce 1 hole per hour in the first example. At that rate, they produce 5 holes in 5 hours. The same 5 men, working at one hole per hour, should be able to produce 100 holes in 100 hours (assuming they don't need sleep, etc.)

If it takes 3 men 6 hours to dig 12 holes how long does it take 2 men to dig 9 holes?
It takes 3 x 6 = 18 man hours to dig 12 holes. Therefore it takes 18/12 = 1.5 man hours to dig 1 hole. To dig 9 holes takes 9 x 1.5 man hours = 13.5 man hours If 2 men are working then they take 13.5/2 = 6.75 hours or 6 hours 45 minutes.
