Harga beli = 180000000 + 10000000 = Rp190.000.000

Harga jual = 95/100 × 190000000 = Rp180.500.000

*5
Harga beli = Rp500.000

Harga jual
(15×10000) + (20×12000) + (25×15000)
150000 + 240000 + 375000
Rp765.000

Harga jual > harga beli ---> untung

Persentase keuntungan
(765000 - 500000)/ 500000 × 100
265000/500000 × 100
53%
