  1. A jacket costs R480. During a sale it is reduced by 15%. What is the sale price?

    Answer: R408

    15% of R480 = R72, so R480 − R72 = R408.

  2. Thandi earns R12 500 per month. She receives a 6% salary increase. What is her new monthly salary?

    Answer: R13 250

    6% of R12 500 = R750, so R12 500 + R750 = R13 250.

  3. South Africa's VAT rate is 15%. An item costs R230 including VAT. What is the price before VAT?

    Answer: R200

    Price before VAT = R230 ÷ 1.15 = R200.

  4. R5 000 is invested at 8% simple interest per year. How much interest is earned over 3 years?

    Answer: R1 200

    Simple interest = P × r × t = R5 000 × 0.08 × 3 = R1 200.

  5. A shop buys goods for R640 and sells them for R800. What is the percentage profit?

    Answer: 25%

    Profit = R160; % profit on cost = (160 ÷ 640) × 100 = 25%.

  6. R8 000 is invested at 10% compound interest per annum. What is the value after 2 years?

    Answer: R9 680

    After 2 years: R8 000 × (1.10)² = R8 000 × 1.21 = R9 680.

  7. The exchange rate is R18.50 per US dollar. A tourist converts R5 550. How many dollars does she receive?

    Answer: 300

    R5 550 ÷ R18.50 per dollar = 300 dollars.
