Answer Key: Primary 5 Mathematics Quiz - Money

Total Marks: 50

Section A: Multiple Choice Questions (Questions 1 to 5)

2 marks each. 1 mark for correct answer only.

1. Answer: B) $2.90

Cost of pen = $0.85 +$ 1.20 = $2.05
Total cost = $0.85 +$ 2.05 = $2.90
Teaching Note: "More than" means addition. First find the cost of the pen, then add both costs.
Common Mistake: Students may forget to add the pencil's cost after finding the pen's cost.

2. Answer: C) $13.90

Cost of apples = 3 × $2.50 =$ 7.50
Cost of oranges = 2 × $3.20 =$ 6.40
Total cost = $7.50 +$ 6.40 = $13.90
Teaching Note: Multiply quantity by unit price for each item, then add the totals.
Common Mistake: Adding the unit prices first (3+2=5, $2.50+$ 3.20= $5.70, 5×$ 5.70=$28.50) is incorrect.

3. Answer: C) $36

Discount amount = 20% of $45 =$ \frac{20}{100} \times 45 = 0.2 \times 45 = $9$
Sale price = $45 -$ 9 = $36
Teaching Note: "Discount" means a reduction. Find the discount amount first, then subtract from the original price.
Alternative Method: Sale price = 80% of $45 = 0.8 ×$ 45 = $36.

4. Answer: B) $15

Money spent on book = $\frac{2}{5} \times \$ 50 = $20$
Remainder after book = $50 -$ 20 = $30
Money spent on meal = $\frac{1}{2} \times \$ 30 = $15$
Money left = $30 -$ 15 = $15
Teaching Note: "Remainder" means what is left. Work step by step: find what was spent, then what is left, then what is spent from the remainder.
Common Mistake: Students may take $\frac{1}{2}$ of the original $50 instead of the remainder.

5. Answer: B) $13.60

Cost of 1 pen = $8.50 ÷ 5 =$ 1.70
Cost of 8 pens = 8 × $1.70 =$ 13.60
Teaching Note: Find the unit cost first (cost per pen), then multiply by the new quantity.
Alternative Method (Ratio): 5 pens : $8.50 = 8 pens :$ x. $x =$ \frac{8}{5} \times 8.50 = $13.60$.

Section B: Short Answer Questions (Questions 6 to 15)

3 marks each. 1 mark for correct method, 1 mark for correct working, 1 mark for correct final answer.

6. Answer: $40.25

Cost of belt = $24.50 -$ 8.75 = $15.75
Total cost = $24.50 +$ 15.75 = $40.25
Teaching Note: "Less than" means subtraction. Find the belt's cost first, then add.
Marking Scheme: 1m for belt cost ($15.75), 1m for correct addition, 1m for final answer.

7. Answer: $40.30

Cost of chicken = 4 × $6.80 =$ 27.20
Cost of fish = 3 × $9.50 =$ 28.50
Total cost = $27.20 +$ 28.50 = $55.70
Change = $100 -$ 55.70 = $40.30
Teaching Note: "Change" is what you get back when you pay more than the total cost. Subtract total cost from the amount paid.
Marking Scheme: 1m for total cost ( $55.70), 1m for subtraction from$ 100, 1m for final answer.

8. Answer: $102

Discount amount = 15% of $120 =$ \frac{15}{100} \times 120 = 0.15 \times 120 = $18$
Discounted price = $120 -$ 18 = $102
Teaching Note: "Discounted price" is the price after the discount is applied.
Alternative Method: Discounted price = 85% of $120 = 0.85 ×$ 120 = $102.
Marking Scheme: 1m for discount amount ($18), 1m for subtraction, 1m for final answer.

9. Answer: $140

Amount saved in February = $\frac{3}{4} \times \$ 80 = $60$
Total saved = $80 +$ 60 = $140
Teaching Note: "Of" in fractions means multiplication. $\frac{3}{4}$ of $80 means$ \frac{3}{4} \times 80$.
Marking Scheme: 1m for February savings ($60), 1m for addition, 1m for final answer.

10. Answer: $1.55

Cost of 1 pen = $18.60 ÷ 12 =$ 1.55
Teaching Note: To find the cost of one item when given the cost of a pack, divide the total cost by the number of items.
Marking Scheme: 1m for correct division setup, 1m for correct calculation, 1m for final answer.

11. Answer: $120

Money spent on dress = 35% of $200 = 0.35 ×$ 200 = $70
Money spent on shoes = 25% of $200 = 0.25 ×$ 200 = $50
Total spent = $70 +$ 50 = $120
Teaching Note: "Altogether" means add. Find each amount separately, then add.
Alternative Method: Total percentage spent = 35% + 25% = 60%. Total spent = 60% of $200 = 0.6 ×$ 200 = $120.
Marking Scheme: 1m for dress cost ( $70), 1m for shoes cost ($ 50), 1m for total ($120).

12. Answer: $40

Cost price per kg = $120 ÷ 50 =$ 2.40
Selling price per kg = $3.20
Profit per kg = $3.20 -$ 2.40 = $0.80
Total profit = 50 × $0.80 =$ 40
Teaching Note: Profit = Selling Price - Cost Price. Find the cost per kg first, then the profit per kg, then multiply by the total kg.
Alternative Method: Total selling price = 50 × $3.20 =$ 160. Profit = $160 -$ 120 = $40.
Marking Scheme: 1m for cost per kg ( $2.40), 1m for profit per kg ($ 0.80), 1m for total profit ($40).

13. Answer: $72

Ratio Ali : Ben = 3 : 5
Ben's share = 5 parts = $45
1 part = $45 ÷ 5 =$ 9
Ali's share = 3 parts = 3 × $9 =$ 27
Total = $27 +$ 45 = $72
Teaching Note: In ratio problems, find the value of 1 part first. Then multiply to find other amounts.
Marking Scheme: 1m for value of 1 part ( $9), 1m for Ali's share ($ 27), 1m for total ($72).

14. Answer: $25.90

Cost of magazine = $\frac{2}{5} \times \$ 18.50 = \frac{2 \times 18.50}{5} = \frac{37}{5} = $7.40$
Total cost = $18.50 +$ 7.40 = $25.90
Teaching Note: "Of" means multiply. Find the magazine cost first, then add.
Marking Scheme: 1m for magazine cost ($7.40), 1m for addition, 1m for final answer.

15. Answer: $39.20

Cost of cloth = 2.5 × $12.80 =$ 32.00
Cost of ribbon = 3 × $2.40 =$ 7.20
Total cost = $32.00 +$ 7.20 = $39.20
Teaching Note: Multiply quantity by unit price for each item. Be careful with decimal multiplication.
Marking Scheme: 1m for cloth cost ( $32.00), 1m for ribbon cost ($ 7.20), 1m for total ($39.20).

Section C: Problem-Solving Questions (Questions 16 to 20)

4 marks each. 1 mark for correct method/working, 1 mark for each correct intermediate step, 1 mark for correct final answer.

16. Answer: $540

Sale price after 25% discount = 75% of $800 = 0.75 ×$ 800 = $600
Additional 10% off sale price = 10% of $600 = 0.1 ×$ 600 = $60
Final price = $600 -$ 60 = $540
Teaching Note: Apply discounts one at a time. The second discount is applied to the already discounted price, not the original price.
Common Mistake: Adding the discounts (25% + 10% = 35%) and applying 35% off $800 gives$ 520, which is incorrect.
Marking Scheme: 1m for sale price ( $600), 1m for additional discount ($ 60), 1m for final price ($540), 1m for correct working.

17. Answer: $48

Let the original amount be $x$ .
Money spent on book = $\frac{1}{4}x$
Remainder after book = $x - \frac{1}{4}x = \frac{3}{4}x$
Money spent on pen = $\frac{2}{3} \times \frac{3}{4}x = \frac{1}{2}x$
Money left = $\frac{3}{4}x - \frac{1}{2}x = \frac{1}{4}x = \$ 12$
Therefore, $x = 12 \times 4 = \$ 48$
Teaching Note: Work backwards from the end. The $12 left is$ \frac{1}{4}$ of the original amount. Alternatively, use model drawing to visualise the fractions.
Marking Scheme: 1m for correct fraction of remainder, 1m for finding fraction left ( $\frac{1}{4}$ ), 1m for correct equation, 1m for final answer.

18. Answer: $96

Total cost price = 200 × $0.60 =$ 120
Number sold at $1.20 = 80% of 200 = 0.8 × 200 = 160 oranges
Number sold at $0.80 = 200 - 160 = 40 oranges
Total selling price = (160 × $1.20) + (40 ×$ 0.80) = $192 +$ 32 = $224
Profit = $224 -$ 120 = $104
Teaching Note: Profit = Total Selling Price - Total Cost Price. Calculate each part carefully.
Marking Scheme: 1m for cost price ( $120), 1m for number of oranges at each price (160 and 40), 1m for total selling price ($ 224), 1m for profit ($104).

19. Answer: $12

Ratio Lily : Mary = 2 : 7
Let Lily have 2 units and Mary have 7 units.
After Mary gives $15 to Lily: Lily = 2 units +$ 15, Mary = 7 units - $15
They are equal: 2 units + $15 = 7 units -$ 15
2 units + $15 +$ 15 = 7 units
2 units + $30 = 7 units
5 units = $30
1 unit = $6
Lily at first = 2 units = 2 × $6 =$ 12
Teaching Note: Use the "before and after" method. The difference between Mary and Lily is 5 units. After the transfer, they are equal, meaning Mary gave half the difference to Lily. So 5 units = $30, 1 unit =$ 6.
Marking Scheme: 1m for setting up the equation, 1m for solving for 1 unit ( $6), 1m for Lily's amount ($ 12), 1m for correct working.

20. Answer: Option A gives a lower price. It is $24 lower.

Option A: 20% off $2400 = 80% of$ 2400 = 0.8 × $2400 =$ 1920
Option B: First discount: 10% off $2400 = 90% of$ 2400 = 0.9 × $2400 =$ 2160
Second discount: 10% off $2160 = 90% of$ 2160 = 0.9 × $2160 =$ 1944
Difference = $1944 -$ 1920 = $24
Option A is $24 lower.
Teaching Note: Two successive 10% discounts are NOT the same as one 20% discount. The second 10% is applied to a smaller amount, so the total discount is less than 20%.
Marking Scheme: 1m for Option A price ( $1920), 1m for Option B price ($ 1944), 1m for identifying Option A as lower, 1m for correct difference ($24).
