Primary 6 PSLE Mathematics Quiz - Whole Numbers (Answer Key)

Total Marks: 40
Topic: Whole Numbers (syllabus-first, no past-year evidence used)

Section A Answers (1 mark each)

Q1. Seven million four hundred and eighty-two thousand nine hundred and fifteen.
Teaching note: Read from left: 7 (millions), 482 (thousands), 915 (ones). Hyphenate compound numbers like forty-eight.

Q2. Millions.
Teaching note: Digit 6 is in the 7-digit position from right: millions place.

Q3. 4 800 000.
Working: 4 827 193 → hundred thousand digit is 8, next digit 2 (<5) so round down.
Common mistake: Rounding to 5 000 000 (that is nearest million).

Q4. 42 449.
Working: 3 215 + 48 672 = 51 887; 51 887 − 9 438 = 42 449.

Q5. 84 210.
Working: 2 406 × 35 = 2 406 × 30 + 2 406 × 5 = 72 180 + 12 030 = 84 210.

Q6. 520.
Working: 12 480 ÷ 24 = 520.

Q7. 1.
Working: 16 × 617 = 9 872; 9 873 − 9 872 = 1.

Q8. 3 045 709.
Working: 3 000 000 + 45 000 = 3 045 000; +700 = 3 045 700; +9 = 3 045 709.

Section B Answers (2 marks each)

Q9. $10 700. [2]
Working: 128 400 ÷ 12 = 10 700.
Marking: 1 mark for operation, 1 mark for answer.

Q10. 3 118 km. [2]
Working: 1 245 + 1 873 = 3 118.

Q11. 1 053. [2]
Working: 2 340 − 1 287 = 1 053.

Q12. 10 000 000. [2]
Working: 9 765 432 → million digit 9, next 7 (≥5) round up to 10 000 000.

Q13. 452. [2]
Working: 3 428 − 2 976 = 452.

Q14. 51 588. [2]
Working: 1 204 × 47 = 56 588; 56 588 − 5 000 = 51 588.

Section C Answers (3–4 marks each)

Q15. 3 218 packets. [3]
Working:
Delivered: 12 450 + 23 875 = 36 325.
Remaining: 84 600 − 36 325 = 48 275.
Each mini-mart: 48 275 ÷ 15 = 3 218 (remainder 5, but context implies equal share of whole packets possible; 15×3 218=48 270, 5 left undistributed – accept 3 218 with note).
Marking: 1 mark total delivered, 1 mark remaining, 1 mark final quotient.

Q16. $1 224. [3]
Working: Adults: 6 × 148 = 888. Children: 4 × 84 = 336. Total = 888 + 336 = 1 224.
Marking: 1 mark adults, 1 mark children, 1 mark total.

Q17. 430 000. [3]
Working: Town A rounded: 234 561 → 230 000. Town B: 198 744 → 200 000. Sum = 430 000.
Marking: 1 mark each rounding, 1 mark sum.

Q18. 28 cartons. [3]
Working: Trays: 6 720 ÷ 30 = 224. Cartons: 224 ÷ 8 = 28.
Marking: 1 mark trays, 1 mark cartons, 1 mark answer.

Q19. $5 797. [4]
Working: Spent: 12 375 + 8 640 = 21 015. Remaining: 50 000 − 21 015 = 28 985. Each child: 28 985 ÷ 5 = 5 797.
Marking: 1 mark total spent, 1 mark remaining, 1 mark division, 1 mark answer.

Q20. 5 912 leaflets. [4]
Working: Sent: 45 600 + 38 925 = 84 525. Remaining: 120 000 − 84 525 = 35 475. Each school: 35 475 ÷ 6 = 5 912.5 → since leaflets whole, 5 912 each with 3 left; accept 5 912.
Marking: 1 mark sent, 1 mark remaining, 1 mark division, 1 mark answer.
