A biologist found a pond with frogs. When classifying them by their mass, he noticed the following:
The

50

lightest frogs represented

30\%

of the total mass of all the frogs in the pond, while the

44

heaviest frogs represented

27\%

of the total mass.
As fate would have it, the frogs escaped and the biologist only has the above information. How many frogs were in the pond?
