D Correct answer
Explanation

Let the number of notes be 4x, 3x, 2x. Total value = 20(4x) + 50(3x) + 5(2x) = 80x + 150x + 10x = 240x. 240x = 480, so x = 2. Number of Rs 50 notes = 3x = 3 * 2 = 6.

AI explanation

Let the number of 20, 50 and 5 notes be 4x, 3x and 2x. The total amount is 20 times 4x plus 50 times 3x plus 5 times 2x, which equals 480. Simplifying gives 80x plus 150x plus 10x equals 480, so 240x equals 480. Solving for x gives 2, and the number of 50 notes is 3x, which is 3 times 2. The number of 50 notes is 6.
