Question

Is y larger than 1?
(1) y is larger than 0
(2) $y^2-4>0$

• A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient
• B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient
• C. BOTH statements TOGETHER are sufficient, but NEITHER statement alone is sufficient
• D. Statements (1) and (2) TOGETHER are NOT sufficient

Answer 1

The correct option is D Statements (1) and (2) TOGETHER are NOT sufficient

(2) ⇒y2>4⇒−2<y<2⇒y2>4⇒−2<y<2
(1) ⇒y>0⇒0<y<2⇒y>0⇒0<y<2
Hence, using both the statements we cannot be determined whether y is larger than 1 or smaller than 1.
