Fun With Numbers Riddle: Find the Missing Number in the Table

The number in the third column is the difference between the two digits of the product of the numbers in the first 2 column.

So let’s test this in the first row;

3 x 6 = 18 :: 8 – 1 = 7

Similarly for other rows we get;

4 x 5 = 20 :: 2 – 0 = 2;

6 x 2 = 12 :: 2 – 1 = 1;

7 x 4 = 28 :: 8 – 2 = 6.

So we can find the missing number as;

7 x 9 = 63 :: 6 – 3 = 3

Answer = 3.
