Question

VEVERITELE Miti ,Piti si cu Riti s au dus la targul de primavara unde se poate cumpara pe alune.Dupa ce Miti a cheltuit 31 alune, Piti a cheltuit 26 alune iar Riti 33 alune au constatat ca le au ramas nr egal de alune,iar daca aduna toate alunele ramase obtin un nr de 4 ori mai mare decat nr alunelor cheltuite impreuna.Aflati cate alune a avut fiecare la inceput.

Answer 1

La inceput: numar egal de alune ramase + cat au cheltuit

M /----------/ +31

P /----------/ +26

R /----------/ +33

adunam alunele ramase, adica 3 segmente, obtinem un numar de 4 ori mai mult decat cat au cheltuit impreuna:

3segmente=(31+26+33) x 4

3segmente=90x4=360

1segment=360:3=120alune

la inceput au avut:

M 120+31 = 151 alune

P 120+26= 146 alune

R 120+33 = 153 alune

Answer 2

31+36+26=93au cheltuit in total
93×4=372 aveau toți la inceput
372÷3=124 avea fiecare
