The answer is 8 . The trick is : Let the number to the left be A.
Let the number to the right be B.
Then A = B^2 + 3 .

361 -> 22
121 -> 14
81 -> 12
25 -> X

What is the value of X?
The value of X is 8.
Solution:
Squareroot of 361 is 19. So 19+3=22
Squareroot of 121 is 11. So 11+3=14
Squareroot of 91 is 9. So 9+3=12
Squareroot of 25 is 5. So 5+3=8

16 because if we look at patterns and if we divide the first one with the second one then the remainder is 9 and hence if we divide 25 by 16 then remainder will be 9.

The answer is 8. X = 8.

Solution:
The formula is.
y*y -> y + 3

So if y = 19, then
y * y -> y + 3
= 19 * 19 -> 19 + 3
= 361 -> 22

Similarly, if y = 5, then
5 * 5 -> 5 + 3
25 -> 8

So, x = 8

the value for x is 8

19 x 19 = 361
=> 19 + 3 = 22

11 x 11 = 121
=> 11 + 3 = 14

9 x 9 = 81
=> 9 + 3 = 12

therefore
5 x 5 = 25
=> 5 + 3 = 8

the value of X is 8
