The weight of a glass of jar is 10% 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 choices:
A) 1/5  B) 1/3  C) 2/5  D) 1/2  E) 5/9
Let weight of jar filled with beans = 100 g   Weight of jar = 10 g   Weight of coffee beans = 90 g   Weight of jar and remaining beans = 60 g   Weight of remaining beans = 50 g   Fraction remaining = 50/90 = 5/9   Answer is 5/9.
