is it a 600-700 question???
looks like a sub-600 one...
ok so:
(1) y^2 -7y +12=0
factor it: (y-3)(y-4)=0
y=3 or y=4 ->insufficient
(2) clearly insufficient
(1)+(2) y=3 or y=4 insufficient. answer is E.

Statement 1 gives us two values of y = 3 and 4. We need exactly 1 value so this is insufficient.
Statement 2 does not give any important information.
Even when we combine statement 1 and 2, we cannot reach to value of y.
E is the correct answer

Target question: What is the value of y?
Statement 1: y² - 7y + 12 = 0
Factor to get: (x - 3)(x - 4) = 0
So, EITHER x = 3 OR x = 4
Since we can’t answer the target question with certainty, statement 1 is NOT SUFFICIENT
Statement 2: y > 0
Statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined
Statement 1 tells us that EITHER x = 3 OR x = 4
Statement 2 tells us that y is positive
So, it could be the case that x = 3 OR x = 4
Since we still can’t answer the target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E

IMO E
y^2 - 7y + 12
y^2 - 4y - 3y + 12
Y ( y - 4 ) - 3 ( y - 4 )
( y - 4 ) ( y - 3 )
y = 4 , y = 3 - INSUFFICIENT ( X )
2) Y > 0
Still don't know a definite value of Y -- INSUFFICIENT ( X )
Combining 1 and 2
Still having 2 Values - 4 and 3.
