75 / 5 = 15 days for 12 men to build one house. 15x12 = 180 days for 1 man to build 1 house.
180 x 7 = 1260 days for 1 man to build 7 houses. 1260 / 20 = 61 days for 20 men to build 7 houses.

If 10 people can paint 60 houses 120 days how many days will it take 5 people to paint 30 houses?
This was a previous incorrect answer*DIVIDE BY 2! everything is in half. half the people half the houses then it stands to reason HALF THE DAYS!!!!! the answer is 60*.....Actually the correct answer is 120 days. You must analyze the relationship of people per house (10 people build 60 houses=6 houses per person over time span). To prove this just imagine if the question asked how long 1 person would take to build 6 houses. You would not simply divide by 10 to get 12 days.
