Consider the question and two statements given below:<br><br>LCM of two numbers x and y is 481 where x \gt y.<br><br>Question: What is the value of (3x-2y)?<br>Statement-1: y \gt 1.<br>Statement-2: HCF of x and y is 1.<br><br>Which one of the following is <strong>CORRECT</strong> in respect of the question and the statements?

  1. A. Statement-1 alone is sufficient to answer the question
  2. B. Statement-2 alone is sufficient to answer the question
  3. C. Both Statement-1 and Statement-2 are sufficient to answer the question
  4. D. Both Statement-1 and Statement-2 are not sufficient to answer the question

Correct Answer: A. Statement-1 alone is sufficient to answer the question

Explanation

Since 481 = 13 \times 37, possible pairs for (x, y) are (481, 1) and (37, 13). Statement 1 (y \gt 1) uniquely isolates the pair (37, 13), allowing calculation of (3x-2y). Statement 2 (HCF=1) is true for both pairs and is insufficient.
