Logic Puzzle #1 Solution

7 is the answer.

We begin by working our way from right to left on the puzzle. In the last column, we add the numbers from the two rows and carry a digit from the sum forward to the column on the left. We’ve illustrated it in the image below.

Similarly, we add the numbers in the second last column and carry a digit of the total forward to the column on the left. Again, we’ve proven this in the image below.

This logic is repeated for the remaining rows and columns. We will also receive:

=> 2 + 8 = 10 + 1 (carried over from previous addition) = 11

In the third row, we receive a 1 match. The last digit is carried forward to the column on the left. When we sum the values in the second row, we get:

=> 6 + 7 = 13 + 1 (carried over from previous addition) = 14

In the third row, we have another match of four. The last digit is carried forward to the column on the left. We now add the value in the first row and use the same reasoning to discover the missing number in place of the question mark. The same is illustrated in the image below.

=> 3 + 3 = 6 + 1 (carried over from previous addition) = 7
