Question

6. Calculati suma tuturor numerelor naturale care,inpartite la 6,dau catul 5

Answer 1

Numerele sunt :30 31 32 33 34 35 (se pun si resturile)
 Suma   195

Answer 2

 x : 6 = 5 = > x = 30
x : 6 = 5 r 1 = > x = 5 x 6 + 1 = > x = 31
x : 6 = 5 r 2 = > x = 5 x 6 + 2 = > x = 32
x : 6 = 5 r 3 = > x = 5 x 6 + 3 = > x = 33
x : 6 = 5 r 4 = > x = 5 x 6 + 4 = > x = 34
x : 6 = 5 r 5 = > x = 5 x 6 + 5 = > x = 35
Adunam toti x - sii !!
30 + 31 + 32 + 33 + 34 + 35 = 195
