Question : if 9999 = 4, 8888 = 8, 1816 = 6, 1212 = 0, then 1919 =?

The answer is:

                                    1919=2

Let us assume the numbers as follows:

9=1

8=2

1=0

6=4

2=0

Hence, when we substitute the assumed values in each of the given numbers we obtain the result for each as follows:

1)

9999=1+1+1+1

9999=4

2)

8888=2+2+2+2

8888=8

3)

1816=0+2+0+4

1816=6

4)

1212=0+0+0+0

i.e.

1212=0

5)

1919=0+1+0+1

i.e.

1919=2

Answer

The value of 1919 is 2

Explanation:  

Now find the value of 1919,

1 ⇒ 0

9 ⇒ 1

So, 1919 ⇔ 0101 ⇔ 0+1+0+1 = 2

Therefore, 1919 = 2

Further Explanation

Given, 9999= 4, 8888= 8, 8816= 6, 1212= 0,

If assume 9 as 1 for 9999 and add each 1 to get 4

So,  9999 ⇔ 1111 ⇔ 1+1+1+1 = 4

Therefore, 9 represents 1

If assume 8 as 2 for 8888 and add each 2 to get 8

So,  8888 ⇔ 2222 ⇔ 2+2+2+2 = 8

Therefore, 8 represents 2

If assume 1 as 0 and assume 6 as 2 for 8816 and add each digit to get 6

So,  8816 ⇔ 2202 ⇔ 2+2+0+2 = 6

Therefore, 1 represents 0 and 6 represents 2

If assume 2 as 0 for 1212 and add each digits to get 0

So,  1212 ⇔ 0000 ⇔ 0+0+0+0 = 0

Therefore, 2 represents 0
