Explanation

Let the number of coins be 3x, 2x, 5x. Value = 3x(1) + 2x(0.5) + 5x(0.25) = 252. 3x + x + 1.25x = 252. 5.25x = 252. x = 48. Number of 25p coins = 5 * 48 = 240.

AI explanation

Let the number of 1 rupee, 50 paisa and 25 paisa coins be 3x, 2x and 5x. Their values in rupees are 1(3x), 0.5(2x) and 0.25(5x), giving the equation 3x + x + 1.25x = 252. Solving 5.25x = 252 yields x = 48. The number of 25 paisa coins is 5x, which is 5 times 48, resulting in 240.
