8) persentase kenaikan harga apel
= (42.000 - 35.000)/35.000 x 100%
= 7.000/35.000 x 100%
= 1/5 x 100%
= 20% (D)

9) 500 - (1/4 x 200) = 50 x p
500 - 50 = 50 x p
450 = 50 x p
p = 450 : 50
p = 9 (C)

10) aku adalah bilangan ganjil = x
245 - x = 170
x = 245 - 170
x = 75

11) (750 : 25) - 15 = 50 - n
30 - 15 = 50 - n
15 = 50 - n
n = 50 - 15
n = 35
