Identifying Relevant Information

If you can tell what information is needed, or not needed, you are one step closer to solving the problem. Irrelevant information is sometimes given to mislead you.

Danny drove to the grocery store and bought several bags of chips. In order to determine the amount that he spent at the store, which of the following information do we NOT need?

A) Number of bags of chips that Danny bought
B) Age of car that Danny drove
C) Cost of 1 bag of chips
D) All of the above
E) None of the above

Solution: Clearly, the age of the car doesn't affect the amount spent at the store. The other factors are relevant.The answer is B.
