Jawaban:
1. 83,33%
2. 28,35%
Penjelasan dengan langkah-langkah:
1. beras A = 30 kg × 3.200 = 96.000
beras B = 20 kg × 2.700 = 54.000
harga beli = 96.000 + 54.000 = 150.000
jumlah total beras = beras A + beras B
= 30 kg + 20 kg
= 50 kg
harga jual = 5.500 × 50 kg
= 275.000
keuntungan = harga jual - harga beli
keuntungan = harga jual - harga beli = 275.000 - 150.000
keuntungan = harga jual - harga beli = 275.000 - 150.000 = 125.000
keuntungan = 150.000/100% = 1.500
= 125.000 : 1.500
= 83,33%
2. harga jual semangka =
semangka A = 32 × 6.000 = 192.000
semangka B = 15 × 7.500 = 112.500
jumlah keuntungan = 192.000 + 112.500
= 304.500
semangka busuk = 50 - ( 32 + 15 )
= 50 - 47
= 3 buah
kerugian = 425.000 - 304.500
kerugian = 425.000 - 304.500 = 120.500
kerugian = 425.000 /4 = 100 : 25%
= 106.250 : 25%
= 4.250
presentase = 120.500 : 4.250 = 28,35%
