Total Marks: 50

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.

Section B: Short Answer Questions (20 marks)

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

Question 8

Answer: 5,454

Working:

  8,000
- 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
250 × 2 = 500
500 × 2 = 1,000
1,000 × 2 = 2,000

Section C: Structured Questions (20 marks)

Question 16 (3 marks)

(a) Answer: 156 cupcakes

Working: 1,248 ÷ 8 = 156 cupcakes per box

(b) Answer: 780 cupcakes

Working: Method 1: Cupcakes sold = 3 × 156 = 468 Cupcakes left = 1,248 - 468 = 780

Method 2: Boxes remaining = 8 - 3 = 5 boxes Cupcakes left = 5 × 156 = 780

Question 17 (3 marks)

(a) Answer: 20 books

Working: Amir's books - Devi's books = 45 - 25 = 20 books

(b) Answer: 145 books

Working: Total = 45 + 40 + 35 + 25 = 85 + 60 = 145 books

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.

(c) Answer: Straight angle (or straight line)

Explanation: An angle that measures exactly 180° is called a straight angle.

Question 21 (3 marks)

(a) Answer: 574 apples

Working: Apples after morning sales = 2,450 - 1,876 = 574 apples
