1:2:1 Challenge (Problem 11/2007)...

In each of the 4 boxes below, the top 3 numbers combine to generate the bottom number...Challenge 11

Can you figure out the rule (which is the same for each box) and find the missing number? There are no prizes on offer, just the satisfaction of cracking the code. It's not as easy as it looks. Happy computing!

The solution will be posted on Friday, November 9th at 12 noon GMT.
