X+10x/100=A - A este noul pret dupa prima crestere

A+15A/100=1265  Amplificam cu 100
100A+15A=126500
115A=126500
A=1100

x+10x/100=1100   Amplif cu 100
100x+10x=110000
110x=110000

A + 15A/100 =1265 SIMPLIFICAM CU 5
A +3A/20 = 1265, ADUCEM LA ACELASI NUMITOR
20A + 3A = 25300
23A =25300
A = 25300/23
A = 1100 LEI, 
A + 10A/100 = 1100, SIMPLIFICAM FRACTIA CU 10
A + 1A/10 = 1100, ADUCEM LA ACELASI NUMITOR
10A + 1A = 11000
11 A = 11000
A = 11000/11
A 1000 LEI, PRET INITIAL
