Where is shaded area here? Can someone guide me please?
If the variables, X, Y, and Z take on only the values 10, 20, 30, 40, 50, 60, or 70 with frequencies indicated by the shaded regions above, for which of the frequency distributions is the mean equal to the median?
(A) X only
(8) Y only
(C) Z only
(D) X and Y
(E) X and Z
Can't Recognize Shaded Regions, Help Please

This incomplete question looks like a twist on this question: https://www.beatthegmat.com/psmeanand ... 16119.html
You're right  the figures require shading.

This is an old quant review question:
Mean = 40 (All the same colored ones are multiples of 40 so mean would be evened out to 40)
Median (Mid) = (40 + 40)/2 = 40
Frequency Distribution for Z : Similarly for Z Mean = Median = 40
There's no answer option containing all the three so we need not check Y

Frequency Distribution for X : 10 20 20 30 30 30 40 40 40 40 50 50 50 60 60 70If the variables, X, Y, and Z take on only the values 10, 20, 30, 40, 50, 60, or 70 with frequencies indicated by the shaded regions above, for which of the frequency distributions is the mean equal to the median?
