60 times the weight of each quarter plus the weight of the jar is 52 ounces. 125 times the weight of each quarter plus the weight of the jar is 65 ounces. Put those two statements together and you get 65 times the weight of a quarter is 13 ounces, so a quarter weighs about 0.2 ounces. And you can take it from there I would guess.
