Răspuns :
x-pret initial
x-10/100x=
=x-x/10
se amplifica primul x cu 10
=10x/10-x/10
=9x/10
9x/10=27000
9x=270000
x=30000(pret initial)
x-primul numar
x+1-al doilea numar
x+2=al treilea numar
x+x+1+x+2=132
3x+3=132
3x=129
x=43(primul nr)
43+1=44(al doilea numar)
43+2=45(al treilea numar)
x= suma initiala
x-10x/100=27 000
100x-10x=2 700 000
90x=2 700 000
x=30 000
