Answer 1

1919 = 2 ...............

Answer 2

Here the answer is 1919=2 adhering to the presented values. The determiner of the value of the digits mention here is the circle in it.

In 9999, there are 4 circles. Similarly in 8888 there are 8 circles. In 1816, there are 2 circles, and in 1212, there is no circle.

Following the rule, that is why 1912, the value will be 2. In fact the values are nothing but the number (quantity) of the circles in the 4 digits.
