  8. (C) - Volume = length × width × height = 6 × 4 × 5 = 120 cm³

  9. (B) - Sum of angles = 180°, so third angle = 180° - 75° - 60° = 45°

  10. (D) - Area = length × width = 15 × 8 = 120 m²

  11. (C) - 3.75 + 2.6 = 6.35

  12. (A) - 7/9 - 1/3 = 7/9 - 3/9 = 4/9

  13. (B) - 7:5 ratio with total 48 → 7 parts = 7 × 4 = 28 boys

  14. (D) - Perimeter = 2(12 + 7) = 38 cm

  15. (A) - 3 hours 45 minutes = 3.75 hours at 60 km/h = 225 km

  16. (C) - 85 out of 100 = 85%

  17. (B) - If 1/4 = 18, then whole = 72, so 3/4 = 54

  18. (D) - 0.6 = 6/10 = 3/5

  19. (A) - 8% of 450 = 0.08 × 450 = 36

  20. (C) - 2/5 of remainder: spent 1/4 first, so remainder = 3/4, then 2/5 × 3/4 = 6/20 = 3/10 of total

Section B: Short Answer (30 marks)

21. Nine million, four hundred and sixty-seven thousand, eight hundred and fifty-two

22. a) 84 ÷ 100 × 1000 = 0.84 × 1000 = 840 b) 7.25 × 100 = 725

24. a) 4 2/3 + 2 5/6 = 14/3 + 17/6 = 28/6 + 17/6 = 45/6 = 7 1/2 b) 7/8 × 4 = 28/8 = 3 1/2

25. a) 60% of 225 = 0.6 × 225 = 135 b) 45 out of 180 = 45/180 = 1/4 = 25%

27. Distance = 75 × 2.4 = 180 km

28. Area = 1/2 × 16 × 9 = 72 cm²

Section C: Word Problems (50 marks)

29. Books initially = 25,648 Books donated = 8,375 Books bought = 4,926 Final books = 25,648 - 8,375 + 4,926 = 22,199

  Answer: The library has 22,199 books now.

  Answer: 3/8 of the cake was left.

31. Total students = 360 Boys = 2/5 × 360 = 144 Girls = 360 - 144 = 216

  Girls who wear glasses = 1/3 × 216 = 72
  Boys who wear glasses = 1/4 × 144 = 36
  Total with glasses = 72 + 36 = 108
  
  Answer: 108 students wear glasses.

32. Original price = 250Discount=15250 Discount = 15% of 250 = 0.15 × 250=250 = 37.50 Sale price = 250−250 - 37.50 = 212.50GST=7212.50 GST = 7% of 212.50 = 0.07 × 212.50=212.50 = 14.88 Final price = 212.50+212.50 + 14.88 = $227.38

  Answer: Mrs. Tan paid $227.38.

33. Length = 25 m, Width = 15 m, Height = 3 m

  Floor area = 25 × 15 = 375 m²
  Tiles needed = 375 ÷ 0.25 = 1,500 tiles
  Cost of tiles = 1,500 × $3.50 = $5,250
  
  Paint for walls and ceiling:
  Wall area = 2 × (25 × 3) + 2 × (15 × 3) = 150 + 90 = 240 m²
  Ceiling area = 375 m²
  Total paint area = 240 + 375 = 615 m²
  Paint needed = 615 ÷ 5 = 123 litres
  Cost of paint = 123 × $15 = $1,845
  
  Total cost = $5,250 + $1,845 = $7,095
  
  Answer: The total renovation cost is $7,095.
