Problema Solution

A collection of 45 coins consisting of 5 peso and 10 peso coins has a value of 340 pesos. Find the number of coins of each type.

Answer provided by our tutors

let 'n' represent the number of 5 peso coins, then '45-n' represents the number of 10 peso coins and we have:


340=5n + 10(45-n)

solving for 'n' we have n=22


45-22 = 23


there are 22 5-peso coins and 23 10-peso coins
