The weight of a glass jar is 20% 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 fractional part of the beans remain in the jar?

1/12

1/3

2/5

1/2

2/3

Total weight = weight of coffee jar = 100

Weight of glass jar = 20

Weight of the coffee beans = 80... (100-20)...............(a)

Original total weight = 100

New weight = 60% * 100 = 60

New weight of the beans = 40 ( 60-20).............(b)

Fraction =40/80 =1/2

thanks
