Grandma had made pies for a bake sale. She had carefully put equal amounts of mixture in each pie tin and was now trying to find the weight of the pies.
She had a problem; she only had one $200$ gram weight and one $125$ gram weight.
She found that one pie balanced on the scale with both weights and a quarter of a pie.
How heavy was each pie?
