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