The questions below is followed by two statements, labelled (A) and (B). Decide whether the data given in the statements is sufficient for answering the question.
What does WXY equal?
(A) W=X+Y
(B) WXYZ=6Z

• A. Both statements (A) and (B) together are sufficient to answer the question asked, but neither statement alone is sufficient.
• B. Statement (B) alone is sufficient but statement (A) alone is not sufficient to answer the question asked.
• C. Statement (A) alone is sufficient but statement (B) alone is not sufficient to answer the question asked.
• D. Each statement is sufficient by itself to answer the question asked.

Answer 1

Answer: (B)

Statement (B) alone is sufficient but statement (A) alone is not sufficient to answer the question asked.

Answer 2

First statement alone is insufficient as W, X and Y can be any integer possible.
Statement B : WXYZ = 6Z
=> WXY = 6
Thus, statement B alone is possible to answer the question.

The correct option is (B): Statement (B) alone is sufficient but statement (A) alone is not sufficient to answer the question asked.
