If the data in statement (1) alone is sufficient to answer the question
B)
If the data in statement (2) alone is sufficient to answer the question
C)
If the data in both the statements together are needed to answer the question
D)
If either statement (1) alone or statement (2) alone is sufficient to answer the question
E)
If neither statement (1) nor statement (2) suffices to answer the question
A
Statement I: We have (x + y)2 < (x – y)2
⇒ x2 + y2 + 2xy < x2 + y2 – 2xy
⇒ 4xy < 0 ⇒ xy < 0. Hence statement I is sufficient.
Statement II: It is given that x – y is positive. Now here both x and y can be positive with x > y or x can be positive and y can be negative. So xy can be positive or negative. Therefore statement II is insufficient.
