465 coins consist of 1 rupee, 50 paise and 25 paise coins.
Their values are in the ratio 5 : 3 : 1.
The number of each type of coins respectively is

Let 1 re coin = x, 50p coin =y, 25p coin = z,
x + y + z = 465 and 4x : 2y : z = 5 : 3 : 1 This is the value ratio.
4x : 2y = 5 : 3
12x = 10y
x/y = 5/6
2y : z = 3 : 1
2y = 3z
y/z = 3/2
x : y : z = 5 : 6 : 4 = 31(5 : 6 : 4)
Solving x = 155, y = 186, z = 124 coins

Answer:
155,186,124 numbers of 1 re, 50 paise and 25 paise coins.
