  1. A budget allocates 30% to rent, 25% to food, 15% to transport, and the rest to savings. If income is R16 000, how much is saved?

    Answer: R4 800

    Remaining % = 100 − 70 = 30%; 30% of R16 000 = R4 800.

  2. An investment of R6 000 grows to R7 920 after 2 years of compound interest. What annual interest rate was applied?

    Answer: 15%

    R7 920 = R6 000 × (1 + r)²; (1 + r)² = 1.32; 1 + r ≈ 1.15, so r = 15%.

  3. A pair of shoes costs £45. If R1 = £0.042, what is the price in rands?

    Answer: R1 071.43

    R per pound = 1 ÷ 0.042 ≈ 23.81; R = 45 × 23.81 ≈ R1 071.43.

  4. A laptop is bought on hire purchase: R2 000 deposit plus 24 monthly payments of R450. What is the total cost?

    Answer: R12 800

    Total = R2 000 + 24 × R450 = R2 000 + R10 800 = R12 800.

  5. A price excluding VAT is R260. Which calculation gives the VAT-inclusive price?

    Answer: R260 × 1.15

    VAT-inclusive price = original price × (1 + 0.15) = R260 × 1.15 = R299.

  6. A salary of R22 500 is increased by 8%, then increased again by 5%. What is the final salary?

    Answer: R25 515

    After 8%: R22 500 × 1.08 = R24 300; after 5%: R24 300 × 1.05 = R25 515.

  7. A company's revenue fell from R5.2 million to R4.16 million. What was the percentage decrease?

    Answer: 20%

    Decrease = R1.04m; % decrease = (1.04 ÷ 5.2) × 100 = 20%.
