Explanation

Let the number of 1-rupee, 50-paisa, and 25-paisa coins be x, 8x, and 16x respectively. The total value is x + 0.5(8x) + 0.25(16x) = 9x = 495, which gives x = 55. Thus, the number of 50-paisa coins is 8 * 55 = 440.

AI explanation

Let the number of one-rupee, 50 paisa, and 25 paisa coins be x, 8x, and 16x, respectively. Their values in rupees are x, 4x, and 4x, giving the total amount as x + 4x + 4x = 495, so 9x = 495 and x = 55. The number of 50 paisa coins is 8 multiplied by 55, which equals 440.
