Question

Un numar impartit la 5, 10, 15 care da restul 2!!! Dau coroana, multumesc.

Answer 1

a : 5 = x rest 2 ==> a = 5x+2
a : 10 = y rest 2 ==> a = 10y + 2
a : 15 = z rest 2 ==> a = 15z + 2

a = c.m.m.m.c (5;10;15) + 2
5 = 5
10 = 2 × 5
15 = 3 × 5
-------------
2 × 3 × 5 = 30
deci:
a = 30 + 2 = 32 (numarul cautat)

32 : 5 = 6 rest 2
32 : 10 = 3 rest 2
32 : 15 = 2 rest 2
