Question

daca bunica ar da fiecarui nepot cate 3 tarte, un nepot ar ramane fara tarte.daca ar da fiecarui nepot cate doua tarte, atunci i-ar ramane doua tarte.cate tarte a pregatit bunica?cati nepoti are ea?

Answer 1

3*3+3=
=9+3
=12 tarten a pregatit  bunica
12:3=4 nepoti ar primi cate 3 tarte...=> daca 1 nepot ramane fara tarte,atunci
=> bunica are 4+1=5 nepoti
12:5=2 rest 2...=> daca fiecare nepot prineste cate 2 tarte ,raman 2 tarte

tarte=12
nepoti =5

verificare

12:3=4 nepoti primesc cate 3 tarte si 1 ramane fara
12-(2*5)=
=12-10
=2 tarte raman in plus in cazul in care fiecare nepot primeste cate 2 tarte.
