1.tentukan harga penjualan jika: a.harga pembelian Rp.225.000,00 dan untung 10% b.harga pembelian Rp.650.000,00 dan rugi 5% 2.tentukan harga pembelian jika: a.h

1. (a.) Harga beli = 225.000
Untung 10%

225.000 = 100%
225.000 ÷ 10 = 100% ÷ 10
22.500 = 10%

Harga jual = Harga beli + untung
225.000 + 22.500 = 247.500

(b.) Harga beli = 650.000
Rugi 5%

650.000 = 100%
650.000 ÷ 100 = 100% ÷ 100
6.500 = 1%
6.500 × 5 = 1% × 5
32.500 = 5%

Harga jual = Harga beli - rugi
650.000 - 32.500 = 617.500

2. (a.) Harga jual = 495.000
Untung 10%

100% = x
110% = 495.000

110x = 495.000 × 100
110x = 49.500.000
x = 49.500.000 / 110
x = 450.000

Harga beli = 450.000

(b.) Harga jual = 20.000
Rugi 5%

100% = x
95% = 20.000

95x = 20.000 × 100
95x = 2.000.000
x = 2.000.000 / 95
x = 21,052.63

Harga beli = 21,052.63

3. Dik = 150 mainan dijual dengan total 862.000
Rugi 5%
Dit = Harga beli per mainan
Jwb =
• 100% = x
95% = 862.000

95x = 862.000 × 100
95x = 86.200.000
x = 86.200.000 / 95
x = 907.368,42

Harga beli 150 mainan = 907.368,42

907.368,42 ÷ 150 = 6.049,12
