List I has even number of terms, thus its median is the average of two middle terms (when arranged in ascending/descending order), so median=(6+8)/2=7.

List II has odd number of terms, thus its median is the middle term (when arranged in ascending/descending order). As no other number in the list equal to 7, then x=7.

Answer: B.

median of first set = 6+8 = 14/2 =7

since 2nd set has 5 values, middle value should be median. so x should be 7

Median of List I = 7

List II I exactly list I with the addition of "x"

Median of List I = Median of List II

So, x = 7

Answer = B
