Manu's piggy bank contains Rs. 221 in the form of 50 paise, Rs. 1 and Rs. 2 coins in the ratio of 4 : 3 : 6. What is the number of 50 paise coins in the piggy bank?

Show answer & explanation

Answer: (A) 52

Explanation

Let the numbers be 4k, 3k and 6k. Value = 0.5 × 4k + 1 × 3k + 2 × 6k = 17k = 221, so k = 13. 50-paise coins = 4 × 13 = 52.
