Section A: Multiple Choice (10 marks)

(A) - 4/5 × 3/7 × 5/6 = 60/210 = 2/7
(C) - 55% of 180 = 0.55 × 180 = 99
(B) - Volume = 12 × 8 × 6 = 576 cm³
(B) - Third angle = 180° - 68° - 72° = 40°
(A) - 24:36 = 2:3 (divide by 12)
(B) - 1 eraser = $2, so 15 erasers =$ 30
(B) - 6.25 × 10 = 62.5
(C) - Equilateral triangle angles = 60°
(C) - Area = base × height = 16 × 12 = 192 cm²
(A) - 11/12 - 2/3 = 11/12 - 8/12 = 3/12 = 1/4

Section B: Short Answer (20 marks)

11. 3 2/5 × 2 1/7 = 17/5 × 15/7 = 255/35 = 7 2/7

12. 42% of 250 = 0.42 × 250 = 105 35/140 = 1/4 = 25%

13. Width = 126 ÷ 14 = 9 cm Perimeter = 2(14 + 9) = 46 cm

14. 4.5 hours = 4.5 × 60 = 270 minutes 5200 mL = 5200 ÷ 1000 = 5.2 L

15. Total parts = 7 + 4 = 11 1 part = 132 ÷ 11 = 12 7 parts = 7 × 12 = 84 4 parts = 4 × 12 = 48

Section C: Word Problems (25 marks)

16. Let initial money = x Money spent = 1/2 × x + 3/10 × x = 5/10 × x + 3/10 × x = 8/10 × x Money left = x - 8/10 × x = 2/10 × x = $45 Therefore x =$ 45 × 10/2 = $225

  Answer: Priya had $225 initially.

17. After 30% discount = $250 × 0.7 =$ 175 GST = 8% of $175 =$ 175 × 0.08 = $14 Final amount =$ 175 + $14 =$ 189

  Answer: Final amount paid is $189.

18. Total volume = 6 × 4 × 3 = 72 m³ Current water = 2/3 × 72 = 48 m³ Space remaining = 72 - 48 = 24 m³ In litres = 24 × 1000 = 24,000 L

  Answer: 24,000 more litres needed.

19. Let angles be 3x, 4x, 5x 3x + 4x + 5x = 180° 12x = 180° x = 15° Angles are: 45°, 60°, 75°

  Answer: The three angles are 45°, 60°, and 75°.
