Question

A change purse contains an equal number of pennies, nickels, and dimes. The total value of the coins is `$2.40`. How many coins of each does the purse have?

Answer 1

There are `15` coins of each denomination.

Explanation:

Each penny is one cent, each nickel is `5` cents and each dime is `10` cents

Let there be `k` number of each and therefore their value is

`10k+5k+k=240`

`16k=240`

`k=240/16=15`

Hence, there are `15` coins of each denomination.
