There are two natural numbers x and y, where x \gt y. When x is divided by 6, it leaves the remainder 2 and; when y is divided by 6, it leaves the remainder 3. What is the remainder when (x-y) is divided by 6?

  1. A. 1
  2. B. 3
  3. C. 5
  4. D. Remainder cannot be determined

Correct Answer: C. 5

Explanation

We are given x \equiv 2 \pmod{6} and y \equiv 3 \pmod{6}. Then (x-y) \equiv 2 - 3 \equiv -1 \pmod{6}. Adding 6 to find the positive remainder gives -1 + 6 = 5.
