Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Jawaban:

Mrs. Ani gets Rp 2500000 every month.

Penjelasan dengan langkah-langkah:

Mrs. Ani's total salary every month = s

School fee = 20% × s = (1/5)s

At this point, the remainder of her salary equals to: s - (1/5)s = (4/5)s

Used to buy shoes 10% of it, so the remainder is

= (100-10)% × (4/5)s

= 90% × (4/5)s

= (9/10) × (4/5)s

= (18/25)s

That amount equals to 1800000, so:

(18/25)s = 1800000

18s = 25 ×1800000

s = 25 × 100000 = 2500000

Conclusion: Mrs. Ani gets Rp 2500000 every month.
