Answer Key — Primary 6 PSLE Mathematics Quiz: Whole Numbers

Version 2 of 5 | Total Marks: 70

Section A (2 marks each)

Eight hundred forty-five thousand and twenty-one (2)
67 500 (2)
600 (2)
432 (2)
1, 2, 3, 4, 6, 9, 12, 18, 36 (2)
24 (2)
12 (2)
63 (rule: ×2 then +1) (2)
2⁴ × 3² × 5 (2)
1125 (smallest 4-digit multiple of 225) (2)

Section B (4 marks each)

45 + 90 − 6 = 129 (4)
997 (997 − 3 = 994 = 7 × 142) (4)
42 (HCF × LCM ÷ 12 = 6 × 84 ÷ 12 = 42; check HCF(12,42)=6, LCM=84) (4)
103 chairs (LCM of 9 and 11 = 99; 99 + 4 = 103) (4)
8 × 12 ÷ 6 + 14 = 16 + 14 = 30 (4)

Section C (6 marks each)

Cost per gift = 1215 ÷ 45 = $27; profit per gift = 38 − 27 =$ 11; total profit = 45 × 11 = $495 (6)
Units difference: Jar A has 2 units more than Jar B; moving 120 makes them equal, so 2 units = 240, 1 unit = 120; total = 4 units = 480 marbles (6)
Bags: 840 ÷ 8 = 105; 95 × 6 = $570; remaining 10 × 4 =$ 40; total = $610 (6)
At first: A = 3 units, B = 1 unit. After transfer, B − A difference flips by 180 × 2 = 360; 2 units = 360, 1 unit = 180... verify: A = 3u − 90, B = u + 90, B = 2A → u + 90 = 6u − 180 → u = 54; total = 4 × 54 = 216 buttons (6)
Age gap stays 32 years; in 6 years gap of 32 = 2 units of daughter's future age → daughter will be 16, now 10; Mrs Tan = 10 + 32 = 42 years (6)

Marking note: Award method marks for correct model/unit drawing even if arithmetic slips; deduct 1 mark for missing units in Section C final answers.
