  2. B) 150 minutes

    • 2.5 hours × 60 = 150 minutes

  3. C) 216 cm³

    • Volume of cube = side³ = 6³ = 216 cm³

  4. C) 160 cm³

    • Volume = length × width × height = 8 × 5 × 4 = 160 cm³

  5. D) 3/10

    • 30% = 30/100 = 3/10

  6. B) 20

    • 25% of 80 = 25/100 × 80 = 20

  7. B) 9

    • Red:Blue = 5:3, if 15 red = 5 parts, then 1 part = 3
    • Blue = 3 parts = 3 × 3 = 9

  8. C) 3,200 mL

  2. Water tank problem: [8 marks] a) Volume = 80 × 60 × 50 = 240,000 cm³ b) Capacity = 240,000 ÷ 1,000 = 240 litres c) Time = 240 ÷ 5 = 48 minutes

  3. Salary breakdown: [9 marks] a) Housing = 35% of 3,600=∗∗3,600 = **1,260** b) Food + Transport = 25% + 15% = 40% of 3,600=∗∗3,600 = **1,440** c) Savings = 100% - 35% - 25% - 15% = 25% of 3,600=∗∗3,600 = **900**
