The correct answer is 50.
There are two ways to solve this kind of problem:
Solution #1: Look at the columns. In the left column, 47 – 3 = 44. In the middle column, 36 – 3 = 33. The pattern is that you subtract 3 as you move down a column.
Thus, ? – 3 = 47 à ? = 50.
Solution #2: Look at the rows. In the top row, 36 – 14 = 22.
In the middle row, 47 – 14 = 33. The pattern is that you subtract 14 as you move left to right across a row.
Thus, ? – 14 = 36 à ? = 50.
Therefore, the correct answer is 50.
