Question

(x+60%)+30%egal 182 6

Answer 1

(x+60:100)+3:10 =182,6
(X+6):10+3:10=182,6
(X+6):10+3=1826
X+6=18230
x=18224

Answer 2

x-pretul initial
60/100×x-scumpirea
y=x+60/100×x- pret dupa scumpire
30/100×y -a doua scumpire
y+30/100×y=182 - pret final
x+60/100×x= x+6x/10
y= x+ 6x/10
y+30/100×y=x+6x/10+30/100(x+6x/10)= x+ 6x/10+ 3/10(x+6x/10)=x+6x/20+3x/10+18x/10=x+3x/10+3x/10+18x/10= x+24x/10= x+ 12x/5=(5x+12x)/5=17x/5
17x/5=182
17x=182×5
17x=910
x=910/17
x=53,52
b) p/100×53,52=182
p/100=182÷53,52
p/100=3,40
p=340%
