Question

Seorang pedagang membeli barang dgn harga Rp.120.000, tentukan harga penjualan barang itu jika: a. pedagang memperoleh untung 33⅓% b.pedagang mengalani rugi 12½% .. plis bantu

Answer 1

Harga beli = a = 120000
Harga jual = b

#a

laba = 33 1/3 % a

Harga jual
= harga beli + laba
= a + 33 1/3 % a
= 133 1/3 % a
= 133 1/3 % × 120000
= 160000

#b

Rugi = 12,5 % a

Harga jual
= a - 12,5% a
= 87,5% a
= 87,5 % × 120000
= 105000
