Question

11×11=4 22×22=16 33×33=18 44×44=19 55×55=?

Answer 1

20 is the answer......................

Answer 2

The answer to this question is 10. It is because the other conditions are based on the similar technique.

For example, When we multiple 11 by 11, we can get the answer as 121.

We need to consider the three digit number as a separate 3 digits and add them. Finally, we can get the answer as 4.  

If we apply the same technique for 55x55, we can get 3025. When we add the numbers, we can get 10.
