SOLUTION
946 oranges.

PROBLEM # 2
Farmer Ram has a chicken farm. On a certain day, Ram calculates in how many days he will run out of chicken-food. He notices that if he would sell 75 of his chickens, he could feed the remaining chickens twenty days longer with the chicken-food he has, and that if he would buy 100 extra chickens, he would run out of chicken-food fifteen days earlier.

The Question: How many chickens does farmer Ram have?

SOLUTION 
300 chickens.
