Subject: Mathematics
Level: Primary 3
Paper: Practice Paper 2 (Version 2 of 5)
Total Marks: 50

SECTION A: Multiple Choice Questions (15 marks)

Question 1

Answer: (2) tens
Explanation: In 6 482, the digits from right to left are: 2 (ones), 8 (tens), 4 (hundreds), 6 (thousands). The digit 8 is in the tens place.
Marks: 1

Question 2

Answer: (4) 5 000
Explanation: The digit 5 is in the thousands place. Its value is 5 × 1 000 = 5 000.
Marks: 1

Question 3

Answer: (3) 3 284
Explanation: Compare thousands (all 3), then hundreds: 2 < 4 < 8. So 3 284 is the smallest.
Marks: 1

Question 4

Answer: (1) 4 123, 4 231, 4 312, 4 321
Explanation: Ascending order means smallest to largest. Compare hundreds: 1 < 2 < 3. For 4 312 and 4 321, compare tens: 1 < 2.
Marks: 1

Question 5

Answer: (2) 2 770
Explanation: The ones digit is 4 (< 5), so round down the tens digit stays 6? Wait: 2 764, ones digit is 4, which is less than 5, so round down to 2 760. Let me recheck. 2 764: ones digit = 4 < 5, so round down → 2 760. But option (1) is 2 760. Let me check the options again.
Correction: 2 764 rounded to nearest ten: ones digit is 4 (< 5), so round down → 2 760. Answer should be (1) 2 760.
Marks: 1

Question 6

Answer: (2) 5 900
Explanation: The tens digit is 3 (< 5), so round down the hundreds digit. 5 839 → 5 800? Wait: hundreds digit is 8, tens digit is 3. Since 3 < 5, round down → 5 800. But option (1) is 5 800. Let me recheck. 5 839: look at tens digit (3). 3 < 5, so round down to 5 800. Answer should be (1) 5 800.
Correction: Answer: (1) 5 800
Marks: 1

Question 7

Answer: (1) 1 234, 1 334, 1 434, 1 534
Explanation: Each number increases by 100. The hundreds digit increases by 1 each time: 2, 3, 4, 5. Other options have inconsistent jumps.
Marks: 1

Question 8

Answer: (2) 5 400
Explanation: The pattern decreases by 200 each time: 6 000 → 5 800 → 5 600 → 5 400 → 5 200.
Marks: 1

Question 9

Answer: (3) 0 hundreds
Explanation: In 7 045: 7 (thousands), 0 (hundreds), 4 (tens), 5 (ones). The digit 0 is in the hundreds place, so it stands for 0 hundreds.
Marks: 1

Question 10

Answer: (1) 4 326
Explanation: 4 000 + 300 + 20 + 6 = 4 326.
Marks: 1

Question 11

Answer: (2) 400
Explanation: 3 456 = 3 000 + 400 + 50 + 6. The missing part is 400 (the hundreds value).
Marks: 1

Question 12

Answer: (1) 7 200
Explanation: Value of 8 in 8 246 = 8 000 (thousands place). Value of 8 in 3 852 = 800 (hundreds place). Difference = 8 000 - 800 = 7 200.
Marks: 1

Question 13

Answer: (2) 2 375
Explanation: Smallest 4-digit even number: thousands digit must be smallest non-zero digit (2). For even number, ones digit must be even. Remaining digits: 3, 7, 5. Only even digit is 2 (already used). Wait: digits are 3, 7, 2, 5. Even digits: 2. So ones must be 2. But 2 is needed for thousands to be smallest. Let's check: smallest thousands = 2. Then remaining: 3, 7, 5. Need even ones digit, but none left. So 2 must be in ones place for even. Then thousands = 3 (next smallest). Number: 3 _ _ 2. Remaining: 7, 5. Smallest: 3 5 7 2 = 3 572. But options are all 2xxx. Let me re-read: "Form the smallest 4-digit even number using the digits 3, 7, 2, 5." All options start with 2. If thousands is 2, remaining 3,7,5 for hundreds, tens, ones. Ones must be even, but no even digits left. This is impossible. Unless... the question means we can repeat digits? No, "using the digits" typically means each once. Let me check options: (1) 2 357 (odd), (2) 2 375 (odd), (3) 2 537 (odd), (4) 2 573 (odd). All are odd! There's an error in the question or options. The smallest even number would need 2 in ones place: 3 572, 3 752, 5 372, 5 732, 7 352, 7 532. Smallest is 3 572. But not in options. Perhaps the question meant "odd"? If odd: smallest 4-digit odd with 2 in thousands: 2 357 (ends in 7, odd). That's option (1). But question says "even". I'll assume typo and answer for odd, or note the issue. For answer key, I'll state the correct mathematical answer.
Correction: The question has an error - no even number can be formed with 2 in thousands place using these digits once each. The smallest 4-digit odd number is 2 357 (option 1). If "even" is correct, answer is 3 572 (not listed).
Marks: 1

Question 14

Answer: (1) 90
Explanation: 2 435 - 2 345 = 90.
Marks: 1

Question 15

Answer: (3) 6 051
Explanation: Numbers rounding to 6 000 (nearest hundred) are from 5 950 to 6 049. Check options: 5 449→5 400, 5 949→5 900, 6 051→6 100? Wait: 6 051, tens digit is 5, so round up to 6 100. 6 549→6 500. None give 6 000? Let me recheck: 5 950 to 6 049 round to 6 000. 5 949 rounds to 5 900. 6 051 rounds to 6 100. 6 049 would round to 6 000. But 6 051 is not in range. Option (2) 5 949 rounds to 5 900. Option (3) 6 051 rounds to 6 100. Hmm. 5 950 is the lower bound. 5 949 is one less. Perhaps the question means "could be" and 5 949 is closest? No, rounding rules are strict. Let me check: 5 949, hundreds digit 9, tens digit 4 < 5, round down to 5 900. 6 051, hundreds digit 0, tens digit 5 ≥ 5, round up to 6 100. There's no correct answer among options. Unless... 5 949 is meant to be 5 950? Or 6 051 is meant to be 6 049? I'll note the issue. For 6 000, valid numbers: 5 950-6 049. None of the options fall in this range.
Correction: The question options appear flawed. 5 949 rounds to 5 900. 6 051 rounds to 6 100. No option rounds to 6 000.
Marks: 1

SECTION B: Short Answer Questions (20 marks)

Question 16

Answer: Seven thousand and eighty-nine
Explanation: 7 089 = 7 000 + 80 + 9. In words: "Seven thousand" (for 7 000), "and" (before tens/ones when hundreds is zero), "eighty-nine" (for 89).
Marks: 2 (1 for "seven thousand", 1 for "eighty-nine" with correct "and" usage)

Question 17

Answer: 5 604
Explanation: Five thousand = 5 000, six hundred = 600, four = 4. Total = 5 000 + 600 + 4 = 5 604. Note: "six hundred and four" means 604, not 600 and 4 separately.
Marks: 2

Question 18

(a) Answer: 7
(b) Answer: 20
Explanation: In 4 729: 4 (thousands), 7 (hundreds), 2 (tens), 9 (ones). (a) Hundreds place digit is 7. (b) Digit 2 is in tens place, value = 2 × 10 = 20.
Marks: 2 (1 each)

Question 19

Answer: 3 842, 3 824, 3 482, 3 428
Explanation: Descending = largest to smallest. Compare hundreds: 8 > 4. For 3 842 and 3 824: compare tens: 4 > 2. For 3 482 and 3 428: compare tens: 8 > 2.
Marks: 2

Question 20

Answer: 7 900, 7 700
Explanation: Pattern decreases by 200 each time: 8 500 - 200 = 8 300, 8 300 - 200 = 8 100, 8 100 - 200 = 7 900, 7 900 - 200 = 7 700.
Marks: 2 (1 each)

Question 21

Answer: 4 570
Explanation: 4 567, ones digit = 7 (≥ 5), so round up the tens digit: 6 → 7. Result: 4 570.
Marks: 2 (1 for method, 1 for answer)

Question 22

Answer: 3 500
Explanation: 3 482, tens digit = 8 (≥ 5), so round up the hundreds digit: 4 → 5. Result: 3 500.
Marks: 2 (1 for method, 1 for answer)

Question 23

Answer: 6 060
Explanation: Value of 6 in 6 342 = 6 000 (thousands place). Value of 6 in 2 468 = 60 (tens place). Sum = 6 000 + 60 = 6 060.
Marks: 2 (1 for each value, 1 for sum - but total 2 marks, so 1 for correct values, 1 for correct sum)

Question 24

Answer: 8 641
Explanation: Largest 4-digit odd number: thousands = largest digit (8), hundreds = next largest (6), tens = next (4), ones = must be odd, remaining digit is 1 (odd). So 8 641.
Marks: 2
