Harga beli = Rp450.000 x 100 = Rp45.000.000
Harga jual = Rp56.250.000
Keuntungan = Rp56.250.000 - Rp45.000.000 = Rp11.250.000
% = 11.250.000 x 100% = 25%
       45.000.000

Jdi gni 450.000 x 100 = 45.000.000
<=> 56.250.000 - 45.000.000 = 11.250.000 (keuntungan nya)
=> 11.250.000 : 450.000 = 25
 jdi persentase nya 25%
