Answer 1

Răspuns:

Explicație pas cu pas:

a)

P*110/100 = 132 lei

P = 132*100/110 = 120 lei

b)

P*70/100 = 147 lei

P = 147*100/70 = 210 lei

c)

P*110/100*110/100 = 363 lei

P = 363*100*100/(110*110) = 300 lei

d)

P*90/100*90/100 = 162

P = 162*100*100/(90*90) = 200 lei

e)

P*80/100*110/100 = 145,2 lei

P = 145,2*100*100/(80*110) = 165 lei

f)

P*110/100*75/100 = 706,2 lei

P = 706,2*100*100/(110*75) = 856 lei
