1. persentase untung =  \frac{untung}{harga pembelian} x 100%
untung = 960,000 - 800,000 = 160,000
jadi  \frac{160,000}{800,000} x 100%
= 20%

2. harga pembelian =  \frac{100persen}{persen rugi} x rugi
=  \frac{100 persen}{25persen} x 1200,000
= 4 x 1200,000
= 4,800,000

1. HJ-HB = 960.000-800.000 = 160.000 : 800.000 = 20%
2. 1.200.000 • 25 % = 900.000
