Read Solution (Total 1)
-
- 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 - 9 years agoHelpfull: Yes(6) No(3)
