Useful property: If the values in a certain set are equally spaced, then the mean of the set = the median of the set.
Scan the answer choices.....
Notice that, if answer choice E were {8, 9, 10, 11, 12}, then the five values would be equally spaced, in which case the mean = median = 10
However, since the actual set of values is {7, 9, 10, 11, 12}, the median is still 10, but the mean is now slightly less than 10.
Answer: E

Median is middle term and mean or avg is (sum of all term)/ (no. of terms)
(A) {8, 9, 10, 11, 12} ---> Mean = 10 & Median = 10
(B) {8, 9, 10, 11, 13} ---> Mean = 10.2 & Median = 10
(C) {8, 10, 10, 10, 12} ---> Mean = 10 & Median = 10
(D) {10, 10, 10, 10, 10} ---> Mean = 10 & Median = 10
(E) {7, 9, 10, 11, 12} ---> Mean = 9.8 & Median = 10 ---> Correct ans
(A) {8, 9, 10, 11, 12} ---> Mean = 10 & Median = 10
(B) {8, 9, 10, 11, 13} ---> Mean = 10.2 & Median = 10
(C) {8, 10, 10, 10, 12} ---> Mean = 10 & Median = 10
(D) {10, 10, 10, 10, 10} ---> Mean = 10 & Median = 10
(E) {7, 9, 10, 11, 12} ---> Mean = 9.8 & Median = 10 ---> Correct ans
