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

Fact 1) Y is always double X...........Answer to question is always Yes..... Sufff
Fact 2) 2x + 5y = 12 many value for X and Y
X= 1/2, Y=11 ...Answer to question is Yes
X= 11/2, Y= 1/5 .....Answer to question is No
Insuff.
Answer: A

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.

Statement 1) Y is always double X...........Answer to question is always Yes..... Sufficient
Statement 2) 2x + 5y = 12 many value for X and Y
X= 1/2, Y=11/5 ... for this case Y>X
X= 11/2, Y= 1/5 .. for this case X>Y
Statement 2 by itself is Insufficent.
Answer: A

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 = (122x)/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.
