Solve this problem.

Here is a grid of four “boxes”:

You must choose four different digits from 1 – 9 and put one in each box. For example: 5 2

1 9

This gives four two-digit numbers: 52 (reading along the 1st row) 19 (reading along the 2nd row) 51 (reading down the left-hand column) 29 (reading down the right-hand column)

In: this case the sum is 151.

Try a few examples of your own. Is there a quick way to tell if the total is going to be even or odd?

Your challenge is to find four different digits that give four two-digit numbers which add to a total of 100.

How many ways can you find of doing it?
