Question

Ion ,Victor si Marius au colectat 570 kg de maculatura. Marius a colectat de 3 ori mai mult decat Ion, iar Victor de 2 ori mai mult decat Marius.
Cate kg a colectat fiecare?

Answer 1

i+v+m=570kg
m=3i
V=2m=2*3i=6i

i+3i+6i=570kg
10i=570kg
i=570kg/10
i=57kg
m=3i=3*57=171kg
v=2m=2*171=342 kg
