It's clear what the correct answer choice is and how to solve this problem. I think this question is odd. Typically the 2 DS statements do not contrast each other; whereas, in this question, the two statements cannot both be right. Interesting.


Actually the statements do not contradict each other. Consider x = 5.5 and y = 4.5. The would contradict if we assume that a and y are integers but we are not told that they are.


hey Bunuel,

Aren't kilos in this question implied integers?

Thanks

Not necessarily. For example, my weight in kilograms is not an integer :-D

Weights, lengths, volume, surface area, etc are continuous variables and hence need not be integers.
whereas the number of coins, the number of apples are discrete variables, and hence will always be integers.
