Have fun with numbers.

Go through the given equations and find the value of ?

19 + 16 = 51

13 + 13 = 24

12 + 12 = 18

11 + 9 = 33

10 + 10 = ?

Solve this if you are a genius.

Answer:

The riddle has the following logic behind it;

19 + 16 = [(1 + 9) + (1 + 6)] x 3 = [10 + 7] x 3 = 17 x 3 = 51

Similarly;

13 + 13 = [(1 + 3) + (1 + 3)] x 3 = 8 x 3 = 24

Therefore we can find 10 + 10 as;

10 + 10 = [(1 + 0) + (1 + 0)] x 3 = 2 x 3 = 6.

Answer = 6
