Question

daca:
m+o+n+p=820
m-n=n-o=o-p=90
m=?n=?o=?p=?

Answer 1

m+o+n+p=820
m-n=n-o=o-p=90
m=? n=? o=? p=?
m I_I_90_I_90_I_90_I
n I_I_90_I_90_I
o I_I_90_I
p I_I acolada 820
90x6=540(suma partilor cunoscute)
820-540=280(patru parti egale)
280:4=70(p)
70+90=160(o)
70+90+90=250(n)
70+90+90+90=340(m)
