For the third image, 8/20, isn't there an error on the last row of the problem? I am using the XOR method you described (add images and remove overlapping areas). Anyway, I believe the solution is the fifth option.

For the first image, 4/20, answer is 75. For each row, add the two numbers, and then reverse the digits. If the addition results in a number over 100, add the 1 to the last digit, then reverse the resulting two digit number.

For the second 9/20, answer is 62? Multiply 2 numbers outside of circle, subtract the multiplication of the two remaining numbers, and you have the number in the middle of the circle.

Thanks for all the answers, esp. 11/20! I forgot that equation from high school math.
I have an alternate solution for 9/20, the shapes problem.
6 3 5 4 4

1 \ +1 1 ? > +1 (so 4+1 = 5)
So are there multiple solutions to these problems?
