Question 1: A phone originally priced at R3 200 is discounted by 12.5%. What is the discounted price?
- R2 800 (Correct answer)
- R2 880
- R2 750
- R2 960
Correct answer: R2 800
12.5% of R3 200 = R400, so R3 200 − R400 = R2 800.

- R490 (Correct answer)
- R500
- R504

40% of R350 = R140; selling price = R350 + R140 = R490.
Question 3: Which of the following represents a 20% increase on R750?
- R900 (Correct answer)
- R850
- R870
- R920
Correct answer: R900
20% of R750 = R150; R750 + R150 = R900.
Question 4: Sipho's electricity bill was R420 in January and R525 in February. What is the percentage increase?
- 25% (Correct answer)
- 20%
