the weight of a glass of jar is 30 % of the weight of the jar filled with coffee beans. after some of the beans have been removed, the weight of the jar and the remaining beans is 60 % of the original total weight. what fraction part of the beans remain in the jar? Choose the correct choice from the following answers:
A) 1 / 5  B) 1 / 3  C) 2 / 5  D) 1 / 2  E) 3 / 7

the weight of a glass of jar is 30 % of the weight of the jar filled with coffee beans. after some of the beans have been removed, the weight of the jar and the remaining beans is 60 % of the original total weight. what fraction part of the beans remain in the jar?
divide(subtract(60, 30), subtract(const_100, 30))
let weight of jar filled with beans = 100 g weight of jar = 30 g weight of coffee beans = 70 g weight of jar and remaining beans = 60 g weight of remaining beans = 30 g fraction remaining = 30 / 70 = 3 / 7 answer is e .
