How many games did they win?

by Mclaughlin » Sun Aug 03, 2008 11:18 am
Before play-offs, a certain team had won 80 percent of its games. After play-offs, what percent of all its games had the team won?
(1) The team competed in 4 play-off games.
(2) The team won all of its play-off games.


OA is E

not sure why it's E. I put C.

Its E because we never find out how many games they competed in before playoffs. We are just told that 80% are won. Since we don't have the pre-playoff game total, we won't be able to figure out the total number of all games (pre-playoff + post-playoff) unless its given to us. And its not. We would then be trying to solve for three different things...a) pre-playoff game count, b) total game count, c) percent of that total amount.

So the answer is E.
