A calculation that seems obvious but full of pitfalls has started to spread on social networks since a Japanese study found that only 90% of people in their twenties are unable to answer it correctly.
On the web, many users break their teeth on this CM2/6e level calculation.
The terms general intelligence, general mental ability, IQ, or simply intelligence are often used interchangeably to refer to cognitive aptitude testing.
They are commonly offered during recruitment and are similar to logic tests. Logic is indeed an essential quality to develop both in the professional world and for your daily life.
Mathematical aptitude tests are widely used in competitions to reveal your logical skills. The math difficulty levels are deliberately low because it is not advanced math skills that are important, but how you solve the problem with a level of math knowledge equivalent to that of a primary school child. .
This is where the difficulty lies and where the logic test comes into play. With simple elements such as addition and multiplication, one or two basic mathematical rules that everyone knows, you must find the answer logically. If it seems easy at first glance, you quickly realize that you need to increase the parameters to consider in order to solve the problem… with logic.
Logic is a strong indicator that is always measured in IQ tests because it is an essential quality to develop more easily in the professional world or simply to solve the small problems in everyday life. Too often we remain entangled in difficulties because we do not know how to approach the problem, where to start, what steps to take 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 discover the “internal logic” of the test and hidden and thus find the solution.
This problem has gone viral for a few days at first glance, this test is very simple, elementary school level operations, early middle school, but can you find the solution?
