Answer 1

x=suma

x/3+32=Primul nepot

x-x/3-32=2x/3-32=Restul

(2x/3-32)×1/3+32=2x/9-32/3+32=2x/9+64/3=Nepotul al doilea

2x/3-32-2x/9-64/3=4x/9-160/3=Restul

(4x/9-160/3)×1/3+32=4x/27-160/9+32=4x/27+128/9=Nepotul al treilea

x/3+32+2x/9+64/3+4x/27+128/9=x

9x+864+6x+576+4x+384=27x

19x+1824=27x

8x=1824

x=228 lei (Suma initiala)

228×1/3+32=76+32=108 lei Primul nepot

228-108=120

120×1/3+32=40+32=72 lei Al doilea nepot

120-72=48

48×1/3+32=16+32=48 lei Al treilea nepot
