TMI? No... Not Enough Information (NEI) or Extraneous Information (EI)?

At a recent sporting event, 25 athletes won one gold medal each. 25 others won a silver medal. 25 won bronze. 40 athletes did not win any medals. How many medals were awarded?

Answers

a) 115
b) Not enough information
c) 75

The answer is "c"

Note: 

You might be tempted to answer... a) (115) because that is 25 x 3 + 40. You see the numbers in the question and you combine them. 

You might be tempted to answer... b) "Not enough information" because the question involves medals awarded to some athletes and then suddenly some athletes aren't getting any medals.

********If you answer "Not enough information" more than twice on a fifty question exam, you should check the questions again.
