Seorang pedagang mbeli 24 kg salak dg harga Rp150.000 .setengahnya ia jual dgn harga Rp.8000/kg,sepertiganya dijual dgn harga Rp.7000/kg dn sisanya dijual dgn harga Rp.6000/kg.jika seluruh salak habis terjual kejadian yg akan dialami pedagang tsb adl
Setelah dijual ,
1/2 = Rp.8.000/kg
1/3 = Rp.7.000/kg
1 - [1/2 + 1/3] = Rp.6000/kg
Jadi ,
1/2 = 1/2 x 24
1/2 = 12 kg
12 kg = 12 x 8000
12 kg = 96.000
-------------------------------------------------------------------------
1/3 = 1/3 x 24
1/3 = 8 kg
8 kg = 8 x 7000
8 kg = 56.000
-------------------------------------------------------------------------
1 - [1/2 + 1/3] = 1 - [3/6 + 2/6]
1 - [1/2 + 1/3] = 1 - 5/6
1 - [1/2 + 1/3] = 6/6 - 5/6
= 1/6
1/6 = 1/6 x 24
1/6 = 4 kg
4 kg = 4 x 6000
4 kg = 24.000
--------------------------------------------------------------------------
Kesimpulan ,
96.000 + 56.000 + 24.000
= 176.000
Pedagang mengalami keuntungan ,
Sebesar , 176.000 - 156.000 = Rp.20.000
