1. X is an odd integer

What is the value of X, if X and Y are two distinct integers and their product is 30?
1. X is an odd integer
2. X > Y

1) 1*30, 3*10 multiple values not sufficient
2) 30*1 10*3 multiple vaues not sufficient

combined

odd factors of 30 1,3,5,15

only when X=15 Y=2 statifies X>Y

sufficient


C

My ans is (E).
The statement doesn't say that X, Y are positive, hence they could also be negative.

So:

X Y

30 1
-30 -1
15 2
-15 -2
10 3
-10 -3
1 30
-1 -30
2 15
-2 -15
3 10
-3 -10

Stat A is clearly ins.
Stat 2 is ins. too

A+B is ins. as well, because from the table above we have that -1 and -3 are both odd and > than y (-30 and -10 respectively).

Makes sense?

you are right!

Mjjking,
You are very correct on E IMO. Good observation and no wonder u have a 680 to begin with....

Definition of odds and even extend to negative numbers also

Even with both the statements x could be 15 wiht y=2 or x=-5 y=-6.

wow! even i missed on that negative value case! thanks
