MGMAT CAT# 4 Issue

by mhmamdani Thu Mar 04, 2010 1:59 am

Hey,

Ivan operates an ice cream stand in the summertime, selling exclusively chocolate, vanilla and strawberry cones. On a recent afternoon, the ratio of chocolate to vanilla to strawberry cones sold by Ivan was 6 : 3 : 2. How many cones did Ivan sell on that afternoon?

(1) Ivan sold 24 vanilla cones.

(2) Ivan sold twice as many chocolate cones as vanilla cones.


In the question above which appears in ur CAT # 4, the answer is STMT 1 alone is sufficient.

(1)based on the Q and stmt 1 we can conclude that 11x=24 or that x=24/11.

Mathematically the answer is okay, but logically it doesnt make sense because the number of cones sold becomes a decimal and you cant really sell parts of a cone. This is not a complaint or a rant, just something I have noticed so thought would let u guys know.

nope.

statement (1) doesn't say 24 cones total; it says 24 vanilla cones.
the vanilla cones are just 3x, not all of 6x+3x+2x.
therefore, this is 3x = 24, so x = 8. therefore, all the answers are integers as required.

did you look at the answer key before posting this?
