C Correct answer
Explanation

Let the number of coins be 3x (5ps), 2x (10ps), and x (25ps). Total value = (3x × 0.05) + (2x × 0.10) + (x × 0.25) = 0.15x + 0.20x + 0.25x = 0.60x = Rs. 60. Solving: x = 60/0.60 = 100. Therefore, number of 5ps coins = 3x = 300. Option C is correct. Quick check: 300×5ps=Rs.15, 200×10ps=Rs.20, 100×25ps=Rs.25; Total=Rs.60 ✓
