Download Solution PDFGiven:
Coins of 1 rupee, 0.5 rupee, and 0.25 rupee are in the ratio 5:6:8.
Total amount in the bag = ₹420
Calculation:
Total amount = ₹420
⇒ (5x × 1) + (6x × 0.5) + (8x × 0.25) = ₹420
⇒ 5x + 3x + 2x = ₹420
⇒ 10x = ₹420
⇒ x = ₹42
Number of coins of 1 rupee = 5x = 5 × 42 = 210
Number of coins of 0.5 rupee = 6x = 6 × 42 = 252
Number of coins of 0.25 rupee = 8x = 8 × 42 = 336
∴ The correct answer is option (2).
