Développer son raisonnement

Développer son raisonnement

Quelle est la part de l'inné et de l'acquis dans l'intelligence ?

L’intelligence se construit d'abord sur la base de nos expériences. Ainsi il est possible de progresser, dans la vie réelle, mais aussi dans les tests qui sont censés mesurer cette intelligence.
En effet, plus vous vous entraînez et ferez des tests, plus vous optimiserez vos chances de réussite

C’est en forgeant qu’on devient forgeron. Cela dit, un bon test est normalement fait de telle sorte que les questions soient suffisamment déroutantes pour les personnes sur-entraînées.
Certains d’entre vous redoutent particulièrement les épreuves numériques. Pourtant, ce n’est pas forcément la partie la plus difficile, car avec un peu d’entraînement, vous devriez vous en sortir convenablement !

Le principe d’une suite est justement qu’il faut découvrir son principe, c’est-à-dire de quelle façon elle a été constituée. On la classe parfois dans l’intelligence logique.
Il y a en général peu de pièges, et les schémas de constitution sont souvent récurrents. Ils’agit alors d’évaluer la progression d’un terme afin d’en tirer une règle de construction. 

Il peut s’agir d’une  suite « arithmétique » (on ajoute toujours le même nombre) ou « géométrique » (on multiplie par le même nombre). Plus rarement, on peut combiner multiplication et addition.
Lorsque l’observation des écarts ne donnent rien, il faut revenir à un autre principe, par exemple regrouper les termes deux à deux, ou prendre un chiffre une fois sur deux, etc., et observer les alternances. 

Exemple 1 : Chloé a quatre ans. Sa grande sœur Justine est trois fois plus âgée que Chloé. 

Quel âge va avoir Justine lorsqu’elle sera deux fois plus âgée que Chloé ?

Solution : Voici un mode de résolution mathématique, simple et efficace: 

(12+N)=2*(4+N), N représentant le nombre d’année écoulées depuis que Chloé a 4 ans, et Justine 12 ans. 

Il suffit de résoudre cette équation du 1er degré (N=12-2*4=4). Justine aura donc 12+4=16 ans.

Exemple 2 : 124 317 x 19 = ?

Choix :

a ) 2 104 063

b) 23 821 453

c) 2 560 412

d) 2 362 023

Solution : Ceci est impossible à faire de tête, il faut raisonner par approximation.

 125x2=250, d'où 125 000 x 20 = 2 500 000, mais comme on enlève 124 317, le résultat le plus plausible est donc 2 362 023 (réponse d). L’intuition est sollicitée (calcul mental par approximation), mais seule, elle ne suffit pas.
