A riddle has revolutionized social networks by a peculiarity: it has two correct solutions and although one is able to reach most people, there is another one that only manage to solve one of every 1,000 people according to publishes ‘Wikr’. Are you able to reach that solution?

**Solution 1** : Most people start by adding 1 + 4 = 5. To this result, 5 in this case, he adds the result of 2 + 5, in this way we get 12. Following this same process we get the solution of the puzzle, thus 3 + 6 (+12) = 9 + 12 = 21. Finally if we add the result of 21 + 11, we get the answer: 40. This is the solution that most people who participate, the most common.

**Solution 2** : It consists in multiplying the numbers instead of adding them and adding the first of the digits to the result. Thus, multiply 1×4 and add 1, so you get 5; Then multiply 2×5 and add 2, thus obtaining 12; Multiplying 3×6 + 3 yields 21; And multiplying 8×11 and adding 8 gives the final result: 96, different from the first but equal of correct.
