A 1.5 ounce packet of seasoning costs $0.60 and a 4 ounce jar costs $1.44. Which is the better value per ounce?

Correct answer to question 170 (Arithmetic Reasoning): 4 cents per ounce less for the jar

Method

Reduce both containers to a price per ounce before comparing. The packet costs 0.60 divided by 1.5, or 40 cents per ounce, while the jar costs 1.44 divided by 4, or 36 cents per ounce, so the jar is cheaper by 4 cents per ounce.
