## 'Pies' printed from http://nrich.maths.org/

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?
