Question

Tolong ya caranya....

Answer 1

Misalkan harga sebelum diskon = x

30% x + 100000 = 50% x + 50000
100000 - 50000 = 50% x - 30% x
50000 = 20% x 
x = 50000 : 20%
x = 50000 : 20/100
x = 50000 × 100/20
x = 250000

Jawaban: A

Answer 2

Misal :
x = adalah Harga sebelum dipotong

maka :
30% x + 100.000 = 50% x + 50.000
100.000 - 50.000 = 50% x - 30% x
                50.000 = 20% x
                50.000 = 20/100 x
(100/20)(50.000) = x
              250.000 = x

Jawaban A.
