Question

The operator x acts on two integers to give the following outcomes: 3x8=817, 1x6=615, 4x9=918, 15x13=2022. What is the value of 20x22​

Answer 1

Explanation:

It seems that the operator x takes the first digit of the first number, appends it to the second digit of the second number, and then appends the second digit of the first number to the first digit of the second number. Then, the result is obtained by multiplying the two new numbers formed in this way.

Using this rule, we can obtain:

3x8=817 => 38 * 81 = 3081

1x6=615 => 16 * 65 = 1040

4x9=918 => 49 * 18 = 882

15x13=2022 => 153 * 132 = 20286

Therefore, applying the same rule to 20x22, we get:

20x22 = 202 * 022 = 4444

So the value of 20x22 is 4444.
