number of 25 paise coins are 133.33% i.e 4/3 more than that of 1 rupee coins.

Let the number of 1 rupee coins be 3x

Then the number of 25 paise coins will be 7x

The number of 50 paise coins will be 105 - (10x)

1 rupee coins = 3x rupees = 300x paise

25 paise coins = 25(7x) = 175 paise

50 paise coins = [105-(10x)]50 = 5250 - 500x paise

Total amount 50.5 rupees = 5050 paise

5250 - 25x = 5050

Hence, x = 8.

total number of 1 rupee coins = 3x = 24
