i : A = 4 : 7 = 20 : 35
W : i : A = 12:20:35
W + i + A = 134
12x + 20x + 35x = 134
67x = 134
x = 134/67 = 2
W = 12x = 24
i = 20x = 20(2) = 40
A = 35x = 35(2) = 70
usia wati : ibu = 3 : 5 dikali 4
usia ibu : ayah = 4 : 7 dikali 5
perbandingan menjadi = wati : ibu : ayah
= 12 : 20 : 35
jumlh perbandingan = 12+20 + 35 = 67
jumlh umur = 134 thn
maka :
Umur wati = 12/67 x 134 = 24 thn
Umur Ibu = 20/67 x 134 = 40 thn
Umur Ayah = 35/67 x 134 = 70 thn
