The answer could be "8", I'm not sure, but I did notice a couple of patterns in the question.

The number in the first column minus the number in the second column = number in the last column

7-1 = 6
9-5 = 4
7-0 = 7
8-5 = 3

so 9-1 = 8

also the number in the last column minus the number in the next to last column = number in the middle column

6-4 = 2
4-1 = 3
7-2 = 5
3-1 = 2

so 8-4 = 4

i get 8.

7-1 = 6 2+4= 6

same pattern all the way down ( - for the first 2 numbers and + for the second 2)
9-1= 8 4+4= 8

The first three correct entries selected will be declared the winners and will be notified by the competition judges.

I guess it's too late?

Edit: Oh wait, maybe it's a draw and the first three correct answer drawn?

Remember to include your full name and address.

Key word I think is selected, meaning out of the whole lot of entries before the closing date
