Question
A piggy bank holds 20-paise, 50-paise and 2-rupee coins in
the ratio 15:12:9. The total amount inside is Rs. 3006. How many 50-paise coins are there?Solution
ATQ,
Let number of coins = 15x, 12x, 9x
Amount = (15x × 0.20) + (12x × 0.50) + (9x × 2)
⇒ 3x + 6x + 18x = 3006
⇒ 27x = 3006
⇒ x = 111
So, number of 50-paise coins = 12x = 12 × 111 = 1332
