Question

in trei tiruri sunt 26885 kilograme de banane.Daca in cel de al doilea sunt cu 21010 kilograme mai multe decat in primul ,iar in al treilea de doua ori mai mult decat in primul si inca 5075 kilograme,ce cantitate de banane este in fiecare tir?

Answer 1

a=portocale; b=banane; a=2b; a+b=240; 2b+b=240; b=240÷3=80kg de banane; a=2×80=160

Answer 2

a+b+c=26885
b=a+21010
c=2a+5075
a+a21010+c=26885
a+a+21010+2a=26885
4a=26885-21010-5075
26885-21010=5875
5875-5075=800
a=800:4
a=200
b=a+21010
b=200+21010
b=21210
c=2a+5075
c=400+5075
c=5475
5475+21210+200=26885
