Răspuns :
a+b= 175
b = a+25
a+a+25 = 175
2a = 175-25
2a = 150 / :2
a = 75
b = 25+75
b = 100
a |---------|
b |---------|-25-| } 175
175-25= 150 (2 segmente egale cu a)
150 : 2 = 75 kg (a) prima lada
75 + 25 = 100 kg (b) a doua lada
b |---------|-25-| } 175
175-25= 150 (2 segmente egale cu a)
150 : 2 = 75 kg (a) prima lada
75 + 25 = 100 kg (b) a doua lada
