  1. A phone originally priced at R3 200 is discounted by 12.5%. What is the discounted price?

    Answer: R2 800

    12.5% of R3 200 = R400, so R3 200 − R400 = R2 800.

  2. A store marks up goods by 40% on cost. If the cost price is R350, what is the selling price?

    Answer: R490

    40% of R350 = R140; selling price = R350 + R140 = R490.

  3. Which of the following represents a 20% increase on R750?

    Answer: R900

    20% of R750 = R150; R750 + R150 = R900.

  4. Sipho's electricity bill was R420 in January and R525 in February. What is the percentage increase?

    Answer: 25%

    Increase = R105; % increase = (105 ÷ 420) × 100 = 25%.

  5. VAT is 15%. A customer pays R34.50 for milk including VAT. What did the milk cost before VAT?

    Answer: R30

    R34.50 ÷ 1.15 = R30.

  6. R10 000 is borrowed at 12% per annum simple interest. What is the total repayment after 18 months?

    Answer: R11 800

    Interest = R10 000 × 0.12 × 1.5 = R1 800; total = R11 800.

  7. A rand weakens from R15 to R17 per euro. By what percentage did the rand weaken?

    Answer: 13.3%

    Change = 2; % change = (2 ÷ 15) × 100 ≈ 13.3%.
