Section A: Multiple-Choice Questions (15 marks)

1. Answer: (3)
Explanation: In 4 729, the digits from right to left are: 9 (ones), 2 (tens), 7 (hundreds), 4 (thousands). The digit 7 is in the hundreds place.

2. Answer: (1)
Explanation: 5 382 has 5 in the thousands place. In 3 582, 5 is in the hundreds place. In 3 852, 5 is in the tens place. In 3 825, 5 is in the ones place.

3. Answer: (4)
Explanation: The digit 6 in 6 408 is in the thousands place. Its value is 6 × 1 000 = 6 000.

4. Answer: (1)
Explanation: Compare thousands digit (all 3), then hundreds: 428 < 482 < 824 < 842. Order: 3 428, 3 482, 3 824, 3 842.

5. Answer: (1)
Explanation: 5 000 + 300 + 40 + 7 = 5 347.

6. Answer: (2)
Explanation: 7 050 = 70 × 100 + 50 × 1 = 70 hundreds 50 ones.
Option (1): 70 hundreds 5 tens = 7 000 + 50 = 7 050? Wait: 70 hundreds = 7 000, 5 tens = 50, total = 7 050. Actually both (1) and (2) give 7 050. Let me recheck: 70 hundreds = 7 000, 5 tens = 50 → 7 050. 70 hundreds 50 ones = 7 000 + 50 = 7 050. Both are correct? But typically "50 ones" is not standard place value language. The standard partition is 7 thousands 0 hundreds 5 tens 0 ones. However, 70 hundreds 5 tens is also mathematically correct. Let me check the options again. Option (1) says "70 hundreds 5 tens" = 7 000 + 50 = 7 050. Option (2) says "70 hundreds 50 ones" = 7 000 + 50 = 7 050. Both are numerically correct. But in Singapore math, we usually express in standard place value. 7 050 = 7 thousands 5 tens. 70 hundreds = 7 thousands. So 70 hundreds 5 tens is a valid non-standard partition. 70 hundreds 50 ones is also valid but unusual. The question asks "Which of the following is the same as 7 050?" - there should be only one correct answer. Let me reconsider: 70 hundreds 5 tens = 7 000 + 50 = 7 050 ✓. 70 hundreds 50 ones = 7 000 + 50 = 7 050 ✓. Hmm, both work. But typically, "50 ones" would be regrouped as 5 tens. The more conventional answer is (1) 70 hundreds 5 tens. I'll go with (1) as the intended answer since it uses proper place value language (tens, not 50 ones).
Correction: Actually, looking at typical P3 questions, they test understanding that 7 050 = 70 hundreds 5 tens. Option (2) "70 hundreds 50 ones" is technically correct but not the standard way to express it. The answer key should be (1).
Final Answer: (1)
Marking Note: Accept (1) as the best answer. Option (2) is mathematically equivalent but not standard place value representation.

7. Answer: (2)
Explanation: 4 999 rounded to the nearest ten: look at the ones digit (9). Since 9 ≥ 5, round up. 4 999 → 5 000.

8. Answer: (2)
Explanation: Pattern increases by 100 each time: 2 345, 2 445, 2 545, 2 645, 2 745. Missing number is 2 645.

9. Answer: (1)
Explanation: Children = Total − Adults = 3 456 − 1 234 = 2 222.

10. Answer: (3)
Explanation: Tuesday = Monday + 1 345 = 2 850 + 1 345 = 4 195.

11. Answer: (1)
Explanation: 6 000 − 2 478 = 3 522. Check: 3 522 + 2 478 = 6 000.

12. Answer: (3)
Explanation: 246 × 7 = (200 × 7) + (40 × 7) + (6 × 7) = 1 400 + 280 + 42 = 1 722.

13. Answer: (1)
Explanation: 3 456 ÷ 8 = 432 exactly. 8 × 432 = 3 456. Remainder = 0.

14. Answer: (1)
Explanation: 4 320 ÷ 9 = 480. 9 × 480 = 4 320.

15. Answer: (1)
Explanation: Total spent = 2 345 + 1 876 = 4 221. Money left = 5 000 − 4 221 = 779.

Section B: Short-Answer Questions (25 marks)

16. Answer: Eight thousand and sixty-five [1]
Explanation: 8 065 = 8 thousands + 0 hundreds + 6 tens + 5 ones. In words: "Eight thousand and sixty-five". Note: "and" is used before the tens/ones when there are zero hundreds.

17. Answer: 4 099 [1]
Explanation: 3 999 + 100 = 4 099. Adding 100 increases the hundreds digit by 1 (9 hundreds → 10 hundreds = 1 thousand), so 3 999 becomes 4 099.

18. Answer: 4 532 [2]
Working:
7 000 − 2 468
