Ratio of the number of 2 rupee, 1 rupee and 50 paise coins is 3 : 4: 5 |
Let, number of 2 rupee notes = 3x 1 rupee notes = 4x 50 paise coins = 5x |
|
|
Total amount in the bag is Rs. 250 |
Hence, 6x + 4x + 5x/2 = 250 ⇒ x = 20 So, Number of 1 rupee coins = 20 × 4 = 80 |
6x + 4x + 5x/2 = 250 ⇒ 25x/2 = 250 ⇒ x = 20
