Section A: Multiple Choice Questions (10 marks)

---

Question 1

Answer: (C) 700

Working: In the number 6,724:

• 6 is in the thousands place = 6,000
• 7 is in the hundreds place = 700
• 2 is in the tens place = 20
• 4 is in the ones place = 4

The digit 7 is in the hundreds place, so its value is 700.

---

Question 2

Answer: (D) 4,982

Working: Comparing all options:

• 4,892
• 4,928
• 4,289
• 4,982

All start with 4 (thousands). Looking at hundreds: 9 > 8 > 2. So compare 4,928 and 4,982. Looking at tens: 8 > 2. 4,982 is the largest.

---

Question 3

Answer: (A) 2,070

Working:

    345
  ×   6
  -----
  2,070

• 5 × 6 = 30 (write 0, carry 3)
• 4 × 6 = 24, + 3 = 27 (write 7, carry 2)
• 3 × 6 = 18, + 2 = 20

---

Question 4

Answer: (B) 36

Working: 3/4 of 48 = 3/4 × 48 = (48 ÷ 4) × 3 = 12 × 3 = 36

---

Question 5

Answer: (B) 47/20

Working: 2.35 = 235/100 Simplify: 235/100 = 47/20 (divide both by 5)

Check: 47 ÷ 20 = 2.35 ✓

Note: Option (D) 2 7/20 is also correct as a mixed number, but 47/20 is the improper fraction in simplest form.

Question 6

Answer: 5,500

Working: 5,467 → Look at the tens digit (6) Since 6 ≥ 5, round up. 5,467 ≈ 5,500

---

Question 7

Answer: 7,309

Working: Seven thousand = 7,000 Three hundred = 300 Nine = 9 Total = 7,309

- 2,546
-------
  5,454

Using borrowing/regrouping method.

---

Question 9

Answer: 126

Working:

756 ÷ 6 = 126

• 7 ÷ 6 = 1 remainder 1
• 15 ÷ 6 = 2 remainder 3
• 36 ÷ 6 = 6

---

Question 10

Answer: 0.6

Working: 3/5 = 3 ÷ 5 = 0.6

Or: 3/5 = 6/10 = 0.6

---

Question 11

Answer: 6.23

Working:

  2.45
+ 3.78
------
  6.23

• 5 + 8 = 13 (write 3, carry 1)
• 4 + 7 + 1 = 12 (write 2, carry 1)
• 2 + 3 + 1 = 6

---

Question 12

Answer: 40 cm

Working: Perimeter of rectangle = 2 × (length + breadth) = 2 × (12 + 8) = 2 × 20 = 40 cm

---

Question 13

Answer: 81 cm²

Working: Area of square = side × side = 9 × 9 = 81 cm²

---

Question 14

Answer: 5/6

Working: 2/3 + 1/6 = 4/6 + 1/6 (convert 2/3 to 4/6) = 5/6

---

Question 15

Answer: 1,000

Working: Pattern: Each number is doubled (×2)

• 125 × 2 = 250

Question 18 (4 marks)

(a) Answer: 6.25 kg

Working: Total mass = 3.5 + 2.75

  3.50
+ 2.75
------
  6.25

(b) Answer: $28

Working: Cost of chicken = 3.5 × $8 =$28.00

Alternative working: 3.5 × 8 = 3 × 8 + 0.5 × 8 = 24 + 4 = 28

---

Question 19 (4 marks)

(a) Answer: 50 cm

Working: Perimeter of rectangle = 2 × (length + breadth) = 2 × (15 + 10) = 2 × 25 = 50 cm

(b) Answer: 134 cm²

Working: Area of original rectangle = 15 × 10 = 150 cm² Area of cut-out square = 4 × 4 = 16 cm² Area of shaded figure = 150 - 16 = 134 cm²

---

Question 20 (3 marks)

(a) Answer: Angle B

Explanation: A right angle measures exactly 90°.

(b) Answer: Angle C

Explanation: An obtuse angle measures more than 90° but less than 180°. 135° is an obtuse angle.
