Trick
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.Trick
Bob and Joe each took a quiz third period. Bob had a Math quiz and Joe had a Spanish quiz. Both quizzes had ten questions on them. Bob got 3 questions wrong on his quiz and was still able to get a 100. Joe also got 3 questions wrong but got a 70. How did Bob get a 100 when Joe got a 70?
Hint
No extra credit was given to either student. Nice try.Answer
Bob got the 3 extra credit questions wrong on his quiz and was able to get a 100 because extra credit questions only help your score. Joe had no extra credit questions on his quiz, so he lost 3 points for getting the questions wrong.Note: I said no extra credit was given to either student. I never said that extra credit was NOT given.
