Contoh :
Pak Dedi membeli suatu motor bekas dengan harga Rp4.000.000,00. Dalam waktu satu minggu motor tersebut dijual kembali dengan harga Rp4.200.000,00. Tentukan persentase keuntungan Pak Dedi.
Sebelum menentukan persentase keuntungan, kita menentukan keuntungan (U) yang diperoleh Pak Dedi lebih dulu.
i) U = HJ – HB
= 4.200.000 – 4.000.000
= 200.000
(200.000/ 4.000.000) x 100 % = 5 %
Jadi keuntungan pak Dedi 5 %
