x and y are positive number and we need to find which is greater

(1) y = 2x
y > x since both are positive
Sufficient
(2) 2x + 5y = 12
x and y can take different values .
Not sufficient
Answer A

y = 2x suffices for Ans. Second option has 2 variable for 1 equation, hence cannt be solved.
Hence A

2X+5Y=12
Can be 2*5+5*0.4 =12

Re: Which of the positive numbers x or y is greater? [#permalink] New post  04 Jul 2016, 10:33
A is sufficient.

Stmt 1: is valid for both integers and fractions and it can be deduced that y>x.
Stmt 2: not sufficient to prove if x>y or y>x. Hence in sufficient.

Which of the positive numbers x or y is greater?

(1) y = 2x
(2) 2x + 5y = 12

Solution:

Statement 1: x=2,y=4. or x=20.5,y=41. So irrespective of the values this statement holds true. Sufficient.

Statement 2:x=5,y=0.4 or x=1,y=2. Therefore this statement is insufficient.

Therefore the answer is Option A.

St 1: Since both are positive, Y will always be greater than x------ Sufficient.

St 2:
2x+5y = 12
or y = (12-2x)/5

if x =1, y = 2 so y>x
if x= 2, y = less than 2 so y<x Not sufficient

In stat 1 whatever positive value we take y>x hence sufficient
In stat 2 y=2 and x=1 satisfies the equation and x=3.5 and y=1 also satisfies, so we cannot decide which of
x and y is greater hence not sufficient.
A should be the correct choice.

The question would be a little bit trickier if statement 2 would change.

Which of the positive numbers x or y is greater?

(1) y = 2x
(2) 2x + 6y = 12

Statement 2 is still insufficient, but some people will assume that x=1 and y=1, since 12=2*6. But since the question does not state that x and y are integers; S(2) is still insufficient.

So "numbers" on the GMAT does not necessarily mean integers?

Statement 1:
y = x + x and x is confirmed to be positive, so y > x is true. Sufficient.

Statement 2:
We can have y=0.000001 or y = 2. Insufficient.

Ans: A

Solution:

Question Stem Analysis:

We need to determine whether x or y is greater, given that both are positive.

Statement One Alone:

Since both x and y are positive and y is twice x, then y is the greater of the two. Statement one alone is sufficient.

Statement Two Alone:

Statement two alone is not sufficient. For example, if x = 1 and y = 2 (notice that 2(1) + 5(2) = 12), then y is greater. However, if x = 3.5 and y = 1 (notice that 2(3.5) + 5(1) = 12), then x is greater.

Answer: A
