E? becoz the value of x can be anything , we can get the median if we know the value of x.

The set contains

{ Mon, Tue, Wed, Thu, Fri, Sat, Sun }

from condition 1 we know that the set contains
{ 75, 86, 46, 86, x, y, z }
Id does not matter what x, y and z are. The median of this set is 86

What is wrong with this approach ?

Agree with E

Maiden is the middle number in the set, After the set is rearranged
ascending or decending order.

X,Y and Z can be any numbers. Thus, it is not possible to find the maiden
with out knowing all numbers.

I thought the median is simply the middle number no matter what the other numbers are. If the set is odd the number is middle no. if the set is even then average of two middle numbers is the median.

Can you folks clarify this

sorry folks. kpadma is right. Median is simply the middle number when the numbers are arranged in ascending order or descending order.

The answer is E.

I got this wrong. I need to brushup my statistics.

E

Median is always the Middle number when the numbers are re-arrenged from Least to Greatest.

If there are odd terms then it is an middle term otherwise it is the average of the 2 Middle terms
