A. Bagian erfin = 1-1/2-1/3=(6-3-2)/6=1/6 B. Risa 1/2 x 75.000 = 37.500 Mila 1/3 x 75.000 = 25.000 Erfin 1/6 x 75.000 = 12.500

1 = Risa + Milla + Erfin 1 = 1/2 + 1/3 + x 6/6 = 3/6 + 2/6 + x x = 6/6 - 3/6 - 2/6 x = 1/6
Risa : 1/2 x 75.000 = 37.500 Milla : 1/3 x 75.000 = 50.000 Erfin : 1/6 x 75.000 = 12.500
B. Risa 1/2 x 75.000 = 37.500
Mila 1/3 x 75.000 = 25.000
Erfin 1/6 x 75.000 = 12.500
1 = 1/2 + 1/3 + x
6/6 = 3/6 + 2/6 + x
x = 6/6 - 3/6 - 2/6
x = 1/6
Risa : 1/2 x 75.000 = 37.500
Milla : 1/3 x 75.000 = 50.000
Erfin : 1/6 x 75.000 = 12.500
