A and B are cancelling F and G.
So we are left with 0 1 and 2 which is 3 /7 0,42
The median is the middel value so 1. So D

A. 4/7 greater
B. 3/7 greater
C. 1/2 greater
D. 3/7 less
E. 4/7 less
Here median of 7 labelled points = middle point of these 7 points i.e = 1 on the number line
and mean of 7 labelled points = (−4−3+0+1+2+3+4)7 =37
Hence mean is less than median = 1−37 = 47less
Option E
