Correct answer and explanation

Correct answer: 3

Explanation: āœ… Correct Answer: D. 3 šŸ“š Explanation: In a row of 15 chairs, the middle position (P) is 8th from either end. Q is 12th from the right, which means it is 15 - 12 + 1 = 4th from the left. The chairs between the 4th (Q) and 8th (P) are the 5th, 6th, and 7th chairs. Therefore, there are exactly 3 chairs between them. This is a basic ranking and order problem.
