P6 Maths Quiz: PSLE Revision - Answer Key

Section A: Multiple Choice Questions (10 marks)

1. a) 3¾

   • 3.75 = 3 + 0.75 = 3 + ¾ = 3¾

2. b) 96 cm²

   • Area = length × width = 12 × 8 = 96 cm²

3. b) 240 cm

   • 2.4 m = 2.4 × 100 = 240 cm

4. b) 100

   • 40% of 250 = 0.40 × 250 = 100

5. b) 60 km/h

   • Speed = Distance ÷ Time = 180 ÷ 3 = 60 km/h

6. b) 28

   • Ratio boys:girls = 3:4
   • If 3 parts = 21 boys, then 1 part = 7
   • Girls = 4 parts = 4 × 7 = 28

7. c) 125 cm³

   • Volume = side³ = 5³ = 125 cm³

8. c) Obtuse

   • 135° is between 90° and 180°, so it's obtuse

9. b) 11

   • Mean = (8 + 12 + 15 + 9) ÷ 4 = 44 ÷ 4 = 11

10. b) 5

    • 3x + 7 = 22
