Question

Daca a+b+c=28908 ,a+c=10092,iar a este de 12 ori mai mic decat b,afla numerele a,bsi c

Answer 1

a+b+c=28908

a+c=10092   => b = 28908-10092 => b = 18816

12a = b

a = 18816 : 12 => a = 1568

c = 10092 - 1568 => c = 8524

Answer 2

a + b + c = 28 908

a   +     c = 10 092

a = b : 12  

___________________

28 908 - 10 092 = 18 816  ( b )

18 816 : 12 = 1 568  ( a )

10 092 - 1 568 = 8 524 ( c )

Verific:   1 568 +  18 816 + 8 524 = 28 908 → suma celor trei numere
