This is for Q12. Currently not free to do the other ones.

Median is 2.

This must refer to the 8th person since the first five read zero magazines each and the next two read one magazine each.

So, there are 7 people before the 8th person. There must also have been 7 people after so that the 8th person lies nicely in the middle.

x = 7.

If median is 1, this can refer to f the 6th person, 7th person or the “6.5th” person (where the middle two are the 6th and 7th people).

In the case of 6th person, there are 5 people before and 5 people after. This “5 people after” includes the other person who reads 1 magazine and one person who reads 2 magazines.

So, x = 5 - 1 - 1 = 3.

In the case of 7th person, there are 6 people before and 6 people after. This “6 people after” includes the one person who reads 2 magazines.

So, x = 6 - 1 = 5.

In the case of “6.5th” person, where we consider both the 6th and 7th people to be the middle two, there are 5 people before the 6th person and 5 people after the 7th person. This “5 people after” includes the one person who reads 2 magazines.

So, x = 5 - 1 = 4.

Therefore, x can take 3, 4 or 5.
