Răspuns :

a+b=354309
b+c=210904
a+b+c=537309
354309+c=537309
c=537309=354309
c=183000
b+183000=210904
b=210904-183000
b=27904
a+27904+183000=537309
a=537309-210904
a=326405


a+b=90000
b+c=139270
a+b+c=173000
90000+c=173000
c=173000-90000
c=83000
b+83000=139270
b=139270-83000
b=56270
a+56270+83000=173000
a=173000-139270
a=33730
