After drying for two weeks the same items have again been weighted and similarly classified. It is known that the median weight in the first weighting was 20.83 g.
while in the second weighing it was 17.35 g. Some frequencies, a and b, in the first weighing and x and y in the second weighing are missing. It is known that
a = x/3 and b = y/2. Which of the followings is true about the values of the missing frequencies?
