Answer 1

Răspuns:

33kg; 21kg; 18kg.

Explicație pas cu pas:

Fie a,b,c cantitatile initiale in cele 3 lazi.

I. prima operatie:  a-b; b+b; c

II. a-b; 2b-c; c+c;

II. (a-b)+(a-b);  2b-c;  2c-(a-b).

Dupa aceste operatii in lazi sunt cantitati egale de 72:3=24kg.

In prima lada, 2(a-b)=24, deci (a-b)=24:2=12

In lada a 3-a, 2c-(a-b)=2c-12=24, deci 2c=36, c=18.

In lada a 2-a, 2b-c=24, 2b-18=24, deci 2b=42, deci b=21.

In prima lada, 72-(b+c)=72-(21+18)=72-39=33
