My solution:

1.) Pair up the numbers 10-15 with the numbers 1-6 so that you have 6 pairs whose sum is 16.

2.) Form 6 pairs whose sum is 43 from the numbers 16-27, and distribute them in one of $6!=720$ ways to each of the outer hexagons.

3.) Each hexagon now has a sum of $X=75$.

Below is one such way to arrange the numbers:

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
