Puzzle No. 17

Squaring up the squares?
1. For problems 1 & 2, you are given four 'squares' of numbers for each problem. The same mathematical function(s) are applied to each square in each problem, but problems 1 & 2 each use different functions. One of the numbers in the last square in each problem has been replaced with a ?, & you must determine what number should be there instead.


7 3 8 8 5 0 6 ?

6 3 4 2 6 4 9 5

Answer


For each square, multiply the number in the upper left hand corner by the number in the lower right hand corner, & then multiply the result by 3. The first digit of the answer is written in the lower left hand corner, & the second digit of the answer is in the upper right hand corner.
