The number of 5c coins is twice the number of 10c coins. So
let x = number of 10c coins
then 2x = number of 5c coins
The number of 25c coins is 2 more than half the number of 5c coins; that means 2 more than the number of 10c coins. so
x+2 = number of 25c coins
The total value is 1.85 pesos, or 185c, so
So x = 3.
The number of 25c coins is x+2 = 5
The number of 10c coins is x = 3
The number of 5c coins is 2x = 6
