In a bag, there are Rs 1, 50p, and 25p coins in the ratio 5:6:8. If the total amount is Rs 210, find the number of 50p coins.
A126
B105
C168
D200
✓ Correct Answer: A — 126
Value ratio: 5*1 : 6*0.5 : 8*0.25 = 5 : 3 : 2. Sum = 10 units. 10 units = 210, so 1 unit = 21. Value of 50p coins = 3 * 21 = Rs 63. Number of 50p coins = 63 / 0.5 = 126.
