The number of coins of ₹1, ₹5, and ₹10 denominations that a person has are in the ratio 5:3:13. Of the total amount, the percentage of money in ₹5 coins is
(c) is the correct answer.
Ratio of number of coins = 5 : 3 : 13
Let the number of coins be:
₹1 coins = 5k
₹5 coins = 3k
₹10 coins = 13k
Total value from each denomination:
Value from ₹1 coins = 5k × 1 = ₹5k
Value from ₹5 coins = 3k × 5 = ₹15k
Value from ₹10 coins = 13k × 10 = ₹130k
Total amount:
Total = 5k + 15k + 130k = ₹150k
Percentage from ₹5 coins:
Percentage = (15k / 150k) × 100
Percentage = (15 / 150) × 100
Percentage = (1 / 10) × 100
Percentage = 10%
Answer: C) 10%
