Bonjour,
• Nombre entier de 4 chiffres : MCDU
M : millier
C : centaine
D : dizaine
U : unité
• D = 2M
• C = 3U
• la somme de mes chiffres est 11
Qui suis je ?
M + 3U + 2M + U = 11
3M + 4U = 11
M = 1 alors : 11 - 3 x 1 = 8 = 4U donc U = 2
M = 3 alors : 11 - 3 x 3 = 2 = 4U donc U = 1/2 pas possible
M = 1
U = 2
C = 3 x U = 3 x 2 = 6
D = 2 x M = 2 x 1 = 2
Le nombre est : 1622
