Question

15 saci cu faina 19 cu malai cintaresc 2039kg,20 de saci de faina 19 cu malai cintaresc 2364kg,cit cintareste un sac de faina si unul de malai

Answer 1

15 faina.................19 malai.....................2039kg
20 faina..................19 malai....................2364kg
Observam ca avem o diferenta de 5 saci de faina in cel de al doilea caz, sacii de malai ramanand tot 19. Atunci
5 saci de faina......................2364-2039=325kg
1 sac de faina.......................325:5=65 kilograme\
Inlocuim in prima relatie
975 kg(15 saci de faina X65 de kg).........19 malai............2039 kg
                                                                   19 malai=2039-975=1064
                                                                   1 sac malai= 1064:19=56 kg
Verificare
15x65+19x56=2039
