Indirect proportion is more famously known as Inverse Proportion. Inverse proportion is the exact opposite of Direct Proportion. Inverse Proportion -As one quantity increases other quantity decreases. An example problem: If 4 painters can paint a house in 6 days then how many days can 8 painters paint a house of the same size? To solve, use cross product 4 painters=6 days 8 painters=x 4x6=24 24/8=3 To paint the same house,8 painters need 3 days.
The answer is 120. If 10 people can paint 60 houses in 120 days, that means 5 people can paint 60 houses in 240 days (inverse proportion). Therefore, if 5 people were to paint 30 houses it would take 120 days.

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). 5 people would then build 30 houses in the exact same time frame.
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.
