Target question: What is the value of x/y?

Statement 1: x = 2y
Divide both sides by y to get: x/y = 2
Since we can answer the target question with certainty, statement 1 is SUFFICIENT

Statement 2: x = y + 2
You might automatically recognize that there is no way to use this information to determine the value of x/y.

If you don't recognize this, consider these two cases that satisfy statement 2:
Case a: x = 3 and y = 1. In this case, the answer to the target question is x/y = 3/1 = 3
Case b: x = 4 and y = 2. In this case, the answer to the target question is x/y = 4/2 = 2
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT

Asked: If y ≠ 0, what is the value of x/y?

(1) x = 2y
x/y = 2
SUFFICIENT

(2) x = y + 2
x/y = 1 + 2/y
Since y is unknown
NOT SUFFICIENT

IMO A

Re: If y ≠ 0, what is the value of x/y? (1) x = 2y (2) x = y + 2 [#permalink]
Find the value of x/y. Nothing is provided in question stem, lets jump to analyze the statements

statement I: x = 2y
Divide by y => x/y = 2
SUFFICIENT

Hence A or D

Statement 2: x = y + 2
{x,y} could be {1,3} or {2,4} So x/y = 1/3 or 2/4.
