Solution



Given:
    • A set of integers = {97, 98, 56, x, 86}
    • 20 < x < 80

To find:
    • The median of the given set of integers

Approach and Working:
    • As there are 5 terms in the set, the median will be the 3rd term in the series, sorted in ascending or descending order
    • Also, because 20 < x < 80, the least 2 terms will be always x and 56, in any order
    • Hence, the mid-term = 3rd term = 86

Hence, the correct answer is option B.

Answer: B

A. 71
B. 86
C. 91.5
D. 97
E. 397.5


There are 2 scenarios for the given set of integers since 20 < x < 80.
1.20 < x < 56 , Arranging in ascending order, {x,56,86,97,98}, we have median=86
2. \(56\leq{x}\)<80, Arranging in ascending order, {56,x,86,97,98}, we have median=86

Ans. (B)
