Two circles and a rectangle overlap. How many numbers inside the left circle are smaller than the number lying outside every figure?

The number outside every figure is 8. The left circle holds 4, 12, 3 and 9, and only 4 and 3 are smaller than 8, so the answer is 2. 3 also counts 7, which is not inside the left circle, 1 misses one of them, and 4 counts every number in the left circle.
