7. Selesaikan masalah berikut.
Solve the following problems.
(a) Encik Yusof telah menggunakan RM8 000 untuk membeli syer syarikat A. Dia telah mendapat dividen
sebanyak RM200 dalam tempoh dia memegang syer itu. Selepas itu, dia menjual semua syer dan
mendapat RM8 800. Hitung nilai pulangan pelaburan Encik Yusof.
Encik Yusof used RM8 000 to buy shares of company A. He received dividend of RM200 during the time he was holding the shares.
Subsequently, he sold all shares and received RM8 800. Calculate the return on investment for Encik Yusof. SP 3.1.3 TP3
Modal awal/ Initial capital = RM8 000 ROI = RM1 000 × 100%
RM8 000
Jumlah pulangan/ Total return = 12.5% jumlah pulangan × 100%
= RM200 + (RM8 800 – RM8 000) nilai pelaburan awal
total return
= RM200 + RM800 Initial investment value × 100%
= RM1 000
(b) Pada tahun 2015, Puan Zainab membeli unit amanah saham dengan bonusnya sebanyak RM10 000.
Selepas dua tahun, dia menjual semua unit amanah saham itu dan mendapat RM10 400. Dia mendapat
dividen RM350 sebanyak dua kali dalam tempoh dia memegang unit amanah saham itu. Hitung nilai
pulangan pelaburan Puan Zainab.
In year 2015, Puan Zainab bought unit trusts with her bonus of RM10 000. After two years, she sold all the unit trusts and received
RM10 400. She received dividend of RM350 twice during the time she was holding the unit trusts. Calculate the return on investment
for Puan Zainab. SP 3.1.3 TP3
Modal awal/ Initial capital = RM10 000 ROI = RM1 100 × 100%
Jumlah pulangan/ Total return RM10 000
= RM350 × 2 + (RM10 400 – RM10 000) = 11%
= RM700 + RM400
= RM1 100

(c) Encik Tan membuka sebuah kedai farmasi. Pada awal tahun, dia telah membayar RM4 000 untuk
membeli topeng muka untuk simpanan stoknya. Pada akhir tahun, didapati Encik Tan mendapat
RM4 800 selepas semua topeng muka telah habis dijual. SP 3.1.3 TP4
Mr Tan owns a pharmacy. At the beginning of the year, he paid RM4 000 to buy masks as stock. At the end of the year, Mr Tan gained
RM4 800 after selling all the masks.
(i) Hitung nilai pulangan pelaburan Encik Tan.
Calculate the return on investment for Mr Tan.
(ii) Nyatakan satu faktor yang mempengaruhi pulangan pelaburan Encik Tan dan kesannya.
State a factor that can affect the return on investment for Mr Tan and its effect.
RM4 800 – RM4 000
(i) ROI = × 100%
RM4 000
= 20%
(ii) Kejadian pencemaran udara atau jerebu menyebabkan permintaan topeng muka bertambah. Jadi,
harga topeng muka akan bertambah dan pulangan Encik Tan akan bertambah.
The occurrence of air pollution and haze increases masks’ demand. Consequently, mask’s price will hike and this will cause
Mr Tan’s return to increase.
