A bag contains ₹ 1, 50 paise and 25 paise coins in the ratio of 8 : 9 : 11. If the total money in the bag is ₹ 366, then find the number of 25 paise coins?

Let number of ₹ 1 coins = 8k
Number of 50 paise coins = 9k
Number of 25 paise coins = 11k
According to the question,
8k + 9k/2 + 11k/4 = 366
⇒ 32k + 18k + 11k = 1464
⇒ 61k = 1464
∴ k = 1464/61 = 24
∴ Number of 25 paise coins = 11k = 11 x 24 = 264
