##Quiz #110 ##

Jawaban:

Rp 14.692.360,-

Penjelasan dengan langkah-langkah:

Diketahui :

harga jual sepeda motor (hj) = Rp 11.019.270,-

% rugi = 25%

Ditanya :

harga beli sepeda motor (hb) = …

Dijawab :

% rugi = (rugi / harga beli) × 100%

25% = (harga beli – harga jual / harga beli) × 100%

25% / 100% = (harga beli – 11.019.270) / harga beli

1 / 4 = (harga beli – 11.019.270) / harga beli

kali silang

harga beli = 4 × (harga beli – 11.019.270)

harga beli = 4 harga beli – 44.077.080

44.077.080 = 4 harga beli – harga beli

44.077.080 = 3 harga beli

harga beli = 44.077.080 / 3

harga beli (hb) = 14.692.360,–

Jadi :

Harga beli sepeda motor tersebut adalah Rp 14.692.360,–

Jawaban:

ARITMETIKA SOSIAL

Harga Jual = 11.019.270

Rugi % = 25%

Harga Beli = (HB%)/(HJ%) × HJ

Harga beli = 100/(100 – 25) × 11.019.270

Harga beli = 100/75 × 11.019.270

Harga beli = 14.692.360

Jadi harga beli motor tersebut seharga 14.692.360
