Question 1106339
<br>
Note the two different answers from tutors addingup and alan3354.  The answer from addingup is WRONG, for the reason alan3354 says at the beginning of his response.<br>
Unfortunately, common usage incorrectly usually interprets "Jay is 4 times OLDER THAN Chris" as meaning the same thing as "Jay is 4 times AS OLD AS Chris".  But as alan3354 points out, the grammatically correct interpretation is "Jay is 5 times as old as Chris" (Chris's age, plus 4 times more Chris's age).<br>
If this problem comes from a homework assignment, chances are the teacher thinks the wrong answer is the right answer.  If so, you can show him these responses to your question to us.<br>
The problem is widespread.  I have seen problems on practice SAT exams where the incorrect interpretation is used; and just the other day I saw an example in a textbook for high school students working for the international baccalaureate degree in which the incorrect interpretation is used.
