Logic is an essential quality to develop for greater ease in the professional world or simply to solve the small problems of everyday life. . Because very often, we remain entangled in difficulties because we do not know how to take the problem, where to start, what steps to take next to finally find a “logical” solution to our embarrassment.
In the following exercise, your logic will be put to the test. You will have to go beyond the problem as it is presented to try to detect the “internal logic” and hidden of the test and thus find the solution. The data of the problem as presented will not help you solve it.
Only your sense of observation, deduction and logic will allow you to overcome this challenge which, as you will see at the end, is not very difficult. As in many problems of everyday life. Good luck, or rather, good logic.
At first glance this mathematical problem seems quite simple to solve, it just looks like a list of additions. Except that if you look a little closer at the problem you will quickly understand the complexity of this operation.
Since the problem made its comeback on the web, it has once again sparked a lively debate among Internet users.
Obviously, the logic is there in the minds of the creators of the puzzle and it’s really up to you to figure it out!
A lot of people give up before they get to the solution, so if you don’t feel ready, try looking at the picture and take a chance on giving your answer. But only if you have used your intellect and mathematical skills well will you arrive at the solution!
Here is the problem:
1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
8 + 11 = ?
So how much is 8+11?
Here is the solution:
1 + 4 = 5
+ 2 + 5 = 12
+ 3 + 6 = 21
+ 8 + 11 =
Those who find 96 as a result use this slightly more complicated technique:
1 + (1 x 4) = 5
2 + (2×5) = 12
3 + (3×6) = 21
8 + (8 x 11) = 96
Randall’s post got over 1.1 million comments! Most people came up with 40 or 96 as a solution. Which of the two is correct?
Well, both are. It really depends on your view of the problem.
