(1) y < x
(2) x < 2y

Kudos for a correct solution.


is x - y > (x+y)/2 ?
is x >3y ?

(1) y < x Insufficient.
X=4,Y=2 No.
X=4, Y=1 Yes.
(2) x < 2y
Sufficient as we have to find whether x>3y (note x,y are positive) .

Kudos for a correct solution.


rephrased, the question is x > 3y ?

Statement 1:
if x=1, y=1, no
if x=100, y=1 yes
Insufficient

Statement 2:
x < 2y
less than 2y is never larger than 3y
Sufficient

Answer: B

(X+Y)<2(X-Y)?

1. X>Y; X,Y=2,1(No) = 4,1(Yes); Not sufficient
2. X<2Y; above equation will never satisfy;sufficient

Hence answer is B

Reframing the question , we are asked if x > 3y

Statement 1 : x > y. Insufficient.

Statement 2 : 2y > x, If 2y > x, then obviously x is not greater than 3y as x and y are both positive integers. -- SUFFICIENT.
