Math Challenge December 13

Grandma will give us hot chocolate with marshmallows. The number of marshmallows she uses is even. It is a two digit number. It is more than twenty, but less than thirty. The tens digit is half of the ones digit. How many marshmallows did Grandma put in the hot chocolate?
