Section A: Multiple-Choice Questions (20 marks)
1. In the number 68,429, which digit is in the thousands place? [2]
Answer: (2) 8
Explanation:
The place values from right to left are: ones, tens, hundreds, thousands, ten thousands.
In 68,429:
- 9 is in the ones place
- 2 is in the tens place
- 4 is in the hundreds place
- 8 is in the thousands place
- 6 is in the ten thousands place
Marking: 2 marks for correct option.
2. What does the digit 7 stand for in 57,381? [2]
Answer: (4) 7000
Explanation:
The digit 7 is in the thousands place.
Value = 7 × 1,000 = 7,000
Common mistake: Students may confuse "digit" with "place value" or read the place value incorrectly (e.g., thinking 7 is in the hundreds place).
Marking: 2 marks for correct option.
3. Round 42,756 to the nearest hundred. [2]
Answer: (2) 42,800
Explanation:
To round to the nearest hundred, look at the tens digit (5).
- Tens digit is 5, which is ≥ 5, so we round up the hundreds digit.
- Hundreds digit is 7 → becomes 8.
- 42,756 → 42,800
Marking: 2 marks for correct option.
4. Which of the following numbers when rounded to the nearest thousand gives 35,000? [2]
Answer: (2) 34,501
Explanation:
When rounding to the nearest thousand, look at the hundreds digit:
- (1) 34,299 → hundreds digit is 2 (< 5) → rounds to 34,000 ✗
- (2) 34,501 → hundreds digit is 5 (≥ 5) → rounds up to 35,000 ✓
- (3) 35,500 → hundreds digit is 5 (≥ 5) → rounds up to 36,000 ✗
- (4) 35,600 → hundreds digit is 6 (≥ 5) → rounds up to 36,000 ✗
Marking: 2 marks for correct option.

When rounding to the nearest ten, numbers from 2,535 to 2,544 round to 2,540.
- 2,535 → 2,540 (round up)
- 2,544 → 2,540 (round down, since ones digit 4 < 5)

Section C: Long Answer Questions (35 marks)
21. Mr Tan had 28,750 and a motorcycle for $9,480. How much money had he left? [3]
Answer: $6,770
**Working:**2
Total spent = $28,750 + $9,480 = $38,230
Money left = $45,000 − $38,230 = $6,770
Working:
28,750
+ 9,480
--------
38,230 (Total spent)
45,000
- 38,230
--------
6,770 (Money left)
Answer: $6,770
**Marking:**2
- 1 mark for finding total spent ($38,230)
- 1 mark for subtracting from $45,000
- 1 mark for correct final answer ($6,770)
22. A library has 34,560 books. 12,785 books are Chinese books. The rest are English and Malay books. There are 8,430 more English books than Malay books. How many English books are there? [4]
Answer: 15,1022 Working:
Total English + Malay books = 34,560 − 12,785 = 21,775
Let Malay books = 1 unit
English books = 1 unit + 8,430
2 units + 8,430 = 21,775
2 units = 21,775 − 8,430 = 13,345
1 unit (Malay) = 13,345 ÷ 2 = 6,672.5 → Wait, this gives a decimal!
Let me recheck: 21,775 − 8,430 = 13,345. 13,345 ÷ 2 = 6,672.5 → Not a whole number!
There must be an error in the question numbers. Let me recheck the problem.
Total books = 34,560
Chinese = 12,785
English + Malay = 34,560 − 12,785 = 21,775
English = Malay + 8,430
Malay + (Malay + 8,430) = 21,775
2 × Malay = 21,775 − 8,430 = 13,345
Malay = 6,672.5 → Not possible for number of books!
The question has inconsistent numbers. However, following the mathematical working:
Malay books = 6,672.5 (not possible)
English books = 6,672.5 + 8,430 = 15,102.5
Since the question expects a whole number answer, and following the mathematical working:
**Answer: 15,102** (assuming the question expects the mathematical result despite the inconsistency)
**Working:**2
Total English + Malay = 34,560 − 12,785 = 21,775 English = Malay + 8,430 Malay + Malay + 8,430 = 21,775 2 × Malay = 13,345 Malay = 6,672.5 English = 6,672.5 + 8,430 = 15,102.5
**Answer: 15,102** (following mathematical working despite inconsistency)
**Marking:**2
- 1 mark for finding English + Malay total (21,775)
- 1 mark for setting up the comparison model (English = Malay + 8,430)
- 1 mark for finding Malay books (6,672.5) or setting up 2 units = 13,345
- 1 mark for finding English books (15,102.5 → 15,102)

**Answer: 60 bags**
**Marking:**2
- 1 mark for finding total apples (360)

- 1 mark for correct division working
- 1 mark for correct final answer (60 bags)

### 24. The sum of two numbers is 58,400. The difference between the two numbers is 12,800. What is the larger number? [4]
**Answer: 35,600**
**Working:**2
Sum = 58,400 Difference = 12,800 Larger number = (Sum + Difference) ÷ 2 = (58,400 + 12,800) ÷ 2 = 71,200 ÷ 2 = 35,600
**Working:**
Sum + Difference = 58,400 + 12,800 = 71,200 Larger number = 71,200 ÷ 2 = 35,600
**Working:**
35,600
- 22,800
58,400 (Sum check)
35,600
- 22,800
12,800 (Difference check)
**Answer: 35,600**
**Marking:**2
- 1 mark for understanding (Sum + Difference) ÷ 2 = Larger number
- 1 mark for finding Sum + Difference = 71,200
- 1 mark for dividing by 2 to get 35,600

### 25. A stadium has 45,000 seats. On Saturday, $\frac{3}{5}$ of the seats were occupied. On Sunday, 2,450 fewer seats were occupied than on Saturday. How many seats were occupied on both days altogether? [5]
**Answer: 51,550 seats**
**Working:**2
Saturday occupied = Sunday occupied = 27,000 − 2,450 = 24,550 Total occupied = 27,000 + 24,550 = 51,550
**Working:**
Saturday: 45,000 ÷ 5 = 9,000 9,000 × 3 = 27,000
Sunday: 27,000 − 2,450 = 24,550
Total: 27,000 + 24,550 = 51,550
**Working:**
Saturday: 45,000 ÷ 5 = 9,000 9,000 × 3 = 27,000
Sunday: 27,000 − 2,450 = 24,550
Total: 27,000 + 24,550 = 51,550
**Answer: 51,550 seats**
**Marking:**2
- 1 mark for finding Saturday occupied seats (27,000)
- 1 mark for finding Sunday occupied seats (24,550)
- 1 mark for adding both days' occupied seats
- 1 mark for correct addition working
- 1 mark for correct final answer (51,550 seats)
