• B. If statement B ALONE is sufficient to answer the given question, but statement A alone is not.
• C. If both the statements TOGETHER are sufficient to answer the given question, but neither statement alone is sufficient.
• D. If both the statements are INDEPENDENTLY sufficient to answer the given question.

Answer 1

The Correct Option is A

A : When N is divided by 5, the remainder is 3.
N =5k+3 k , where is an whole number.
Let, =Thus, when k =0 N=3
N = 2 9 is divided by 5, remainder = 4 
Statement A alone is sufficient. Clearly, second statement is insufficient, as there can be multiple solutions.
The correct answer is (A) : If statement A ALONE is sufficient to answer the given question, but statement B alone is not.
