A 3x3 grid of numbers with unique row and column medians

Question

Can you place every number from 1 to 9 into a 3x3 grid such that the median of every row and column is a unique value? The median of a row is the number that is greater than one number and smaller than another number in that row (similarly for columns).

Bonus question: Can you find 4 different solutions, such that 2, 3, 4, or 5 are not used as medians?

Good luck!

Answer 1

The medians have values ranging from 2 to 8, so exactly one of these values does not appear as the median of one of the 6 rows/columns.

Here are three templates that allow you to choose any missing median value.

 1 a 5  a
 8 4 6  6
 9 7 b  7

 8 4 5

where {a,b}={2,3}

 1 2 a  2
 3 8 b  b
 c 9 7  7

 3 8 a

where {a,b,c}={4,5,6} with a>b

 1 3 b  3
 2 6 4  4
 9 a 5  a

 2 6 5

where {a,b}={7,8}

For completeness, here are the solutions this produces:

 1 3 5  3     1 2 5  2
 8 4 6  6     8 4 6  6
 9 7 2  7     9 7 3  7

 8 4 5        8 4 5
