Section A: Multiple Choice (10 marks)

1. (A) - 5/6 × 3/4 ÷ 1/2 = 5/6 × 3/4 × 2/1 = 30/24 = 5/4
2. (C) - 45% of 200 = 0.45 × 200 = 90
3. (B) - Volume = 8 × 6 × 5 = 240 cm³
4. (B) - 180° - 75° - 65° = 40°
5. (B) - 18:24 = 3:4 (divide by 6)
6. (C) - 1 book = $63 ÷ 7 =$9, so 12 books = $9 × 12 =$108
7. (B) - 3.75 × 100 = 375
8. (B) - 180° - 65° - 65° = 50°
9. (C) - Area = base × height = 14 × 8 = 112 cm²
10. (A) - 7/8 - 3/4 = 7/8 - 6/8 = 1/8

Section B: Short Answer (20 marks)

11. 2 3/4 × 1 1/3 = 11/4 × 4/3 = 44/12 = 3 2/3

12. 35% of 140 = 0.35 × 140 = 49 28 out of 112 = 28/112 = 1/4 = 25%

13. Width = Area ÷ length = 84 ÷ 12 = 7 cm Perimeter = 2(12 + 7) = 38 cm

14. 2.5 hours = 2.5 × 60 = 150 minutes 3500 mL = 3500 ÷ 1000 = 3.5 L

15. If larger part = 35, and ratio is 5:3 5 parts = 35, so 1 part = 7 Smaller part = 3 × 7 = 21 Total = 35 + 21 = 56

Section C: Word Problems (25 marks)

16. Let initial savings = x Amount used = 3/8 × x + 2/5 × x = 15/40 × x + 16/40 × x = 31/40 × x Amount left = x - 31/40 × x = 9/40 × x = $84 Therefore x =$84 × 40/9 = $373.33 Answer: Ahmad had$373.33 initially.

17. Original price = $60 After 20$60 × 0.8 = $48 GST = 7$48 = $48 × 0.07 =$3.36 Final amount = $48 +$3.36 = $51.36 Answer: Customer pays$51.36.

18. Total volume = 4 × 3 × 2 = 24 m³ Current water = 5/6 × 24 = 20 m³ Space remaining = 24 - 20 = 4 m³ In litres = 4 × 1000 = 4000 L Answer: Tank can hold 4000 more litres.

19. Let the two angles be 2x and 3x 2x + 3x + 60° = 180° 5x = 120° x = 24° First angle = 2 × 24° = 48° Second angle = 3 × 24° = 72° Answer: The two angles are 48° and 72°.
