᯽Ipoteza:᯽

c=10%

m apa= 200g

---------------------

c=md×100/ms

ms=md + m apa

= md + 200g

c=md×100/ms

=md×100/md + 200

__᯽Continuare᯽__

10(md + 200) = 100 md

10 md + 2000g = 100 md

100 md - 10 md = 2000g

90 md = 2000g

md = 22,22 g

ms = md + 200

= 22,22 + 200

= 222,22 g

__᯽Verificare:᯽__

c=md×100/ms

c=22.22×100/222.22

c=10% (aproximativ)

Succes! ♡︎♥︎♡︎
