During the last season, the Tigers won 64% of all their [#permalink] New post 19 Jul 2006, 12:10
During the last season, the Tigers won 64% of all their games. How many games did the Tigers play that season?

1) Tigers won 80 games that season

2) Tigers won 56% of their first 3x games and 76% of their remaining 2x games, where x is an interger and x >24.

Statement 1 is sufficient. .64T = 80

Statement 2 I thought is sufficient as well. I setup the following formula:
56%(3x) + 76%(2x) = 64%(3x+ 2x)

after i set this up, i figured i could solve for x. I got it wrong. can someone tell me why statement 2 is not sufficient then?

thanks
Minhthe

ps. The answer is "A"

This gives, 320x = 320x, which holds true for all values of x, and therefore is not sufficient enough to say what value x takes.

Not 100% sure, we can't solve for X. X could be any # because the proportion would always be 2 to 3?

if the question is correctly typed, then the ans is E.
St 1 insuff: It doesn't give us any info about total # of games
St 2: to which season is it related - last or that?

Pls correct me if I am wrong.
Statement I 0.64 T= 80 which is gives T=80/0.64- SUFFICIENT
Statement II:
0.56(3x) + 0.76(2x) = 80 we can solve for x and the total number of games is 5x..
so ans is D.
Can we get the OA and OE please

if I correctly understood the question, there are 2 different seasons: LAST season and THAT season.

A.

1) 64/100 * Total = 80
Total = 125

2) X can be anything. Hence it is not sufficient to deduce one answer.

Sorry guys, i agree the answer is A. I made the classical mistake of taking statement I into consideration while analyzing statement II.
