There are many benefits to timing your practice, including:

1. y+319 = even, hence y is odd (odd + odd --> even). Thus 3y = oddxodd = odd!

2. Y is not an odd number. If it is odd, then Y should be divisible by 1 and by itself which is also odd!. But it says it is not divisble by any odd number, save 1. Thus it has to be even. Thus the 3x even = even!

Usually in GMAT both the options are congruent, ie they yield the same results. Here option 1 seems to indicate odd, while option 2 seems to indicate even! Thats kind of Weird for GMAT.

Where did you get this Q from? I have not seen this one in Kaplan though, which Kaplan is it?

Here`s a strange one.... If y is a positive integer, is 3y odd? 1. y+319 is even 2. y cannot be evenly divided by any odd number other than 1.

since y is a +ve integer,
from i, y is odd. so suff..
from ii, y is 1. also suff.

if y = 2, then 2 is evenly divided by 1 and 2. so only integer that is evenly (i guess evenly here doesnot mean 2, 4, 6 or so on) divided only by 1 is 1.

1. y+319 is even 2. y cannot be evenly divided by any odd number other than 1.

statement 2 means y is divisible by one and only one odd number that is 1.
--> y can be 1 and 2 ( 4, 8 and all exponents of 2)
--> 3y can be either odd or even
--> insuff

I agree. y=1 satisfies the second condition so we don't really know if 3y is odd or even for that one. In other word the answer should be A. _________________

The OA, according to Kaplan is (D). I am still not convinced...

But as we know, Kaplan is sometimes very erroneous

buddy, our math experts has cleared the confusion and misconception that D is not correct. it was indeed a great discussion.

buddy, this time, the merit goes to Matt as he pointed out the confusion and put forward a thorough consideration
If we stay alert like Matt, keeping an eye on any trickiness of GMAT, we'll certainly ace the maths section
