Answer Key: Primary 6 PSLE Mathematics Quiz - Money

Total Marks: 40

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

Each question carries 1 mark.

1. B) $5.40

Working: Cost of 3 pencils = 3 × $0.80 =$ 2.40. Cost of 2 pens = 2 × $1.50 =$ 3.00. Total cost = $2.40 +$ 3.00 = $5.40.
Teaching Note: Multiply the quantity by the unit price for each item, then add the totals. This is a basic application of multiplication and addition with money.
Marking: 1 mark for correct answer.

2. A) $2.35

Working: Total spent = $6.45 +$ 1.20 = $7.65. Change =$ 10.00 - $7.65 =$ 2.35.
Teaching Note: Change is the difference between the amount paid and the total cost. Add the costs first, then subtract from the amount given.
Marking: 1 mark for correct answer.

3. B) $19.50

Working: Sale price = $24.50 -$ 5.00 = $19.50.
Teaching Note: A reduction means subtracting the discount from the original price.
Marking: 1 mark for correct answer.

4. D) $9.20

Working: Total cost = 4 × $2.30 =$ 9.20.
Teaching Note: Multiply the quantity by the unit price. $2.30 × 4 =$ 9.20.
Marking: 1 mark for correct answer.

5. B) 5

Working: Maximum number = $20 ÷$ 3.50 = 5.714... Since he cannot buy a fraction of a packet, the maximum is 5 packets. Total cost for 5 packets = 5 × $3.50 =$ 17.50, which is less than $20. 6 packets would cost$ 21.00, which is more than $20.
Teaching Note: This is a division problem where the answer must be a whole number. Always check if the next whole number would exceed the budget.
Marking: 1 mark for correct answer.

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

Each question carries 2 marks. 1 mark for correct method, 1 mark for correct answer.

6. $31.35

Working: $18.90 +$ 12.45 = $31.35.
Teaching Note: Adding money values: align the decimal points and add as usual.
Common Mistake: Forgetting to carry over when adding cents (e.g., 90¢ + 45¢ = 135¢ = $1.35).

7. $8.75

Working: Total spent = $28.75 +$ 12.50 = $41.25. Money left =$ 50.00 - $41.25 =$ 8.75.
Teaching Note: First find the total amount spent, then subtract from the original amount.
Common Mistake: Subtracting each item separately from $50 instead of adding them first.

8. $27.40

Working: $35.90 -$ 8.50 = $27.40.
Teaching Note: Discount means subtract from the original price.
Common Mistake: Subtracting incorrectly (e.g., 90¢ - 50¢ = 40¢, but 35 - 8 = 27, so $27.40).

9. $76.00

Working: 5 × $15.20 =$ 76.00.
Teaching Note: Multiply the number of boxes by the cost per box.
Common Mistake: Forgetting to include the cents in the multiplication.

10. $1.20

Working: $7.20 ÷ 6 =$ 1.20.
Teaching Note: To find the unit price, divide the total cost by the number of items.
Common Mistake: Dividing incorrectly (e.g., 7.2 ÷ 6 = 1.2, so $1.20).

11. $74.50

Working: $45.60 +$ 28.90 = $74.50.
Teaching Note: Add the two amounts together.
Common Mistake: Adding cents incorrectly (60¢ + 90¢ = 150¢ = $1.50, so$ 45 + $28 +$ 1.50 = $74.50).

12. $17.20

Working: 8 × $2.15 =$ 17.20.
Teaching Note: Multiply the quantity by the unit price.
Common Mistake: 8 × $2 =$ 16, 8 × $0.15 =$ 1.20, total $17.20.

13. $50.00

Working: 4 × $12.50 =$ 50.00.
Teaching Note: Multiply the number of tickets by the price per ticket.
Common Mistake: 4 × $12 =$ 48, 4 × $0.50 =$ 2.00, total $50.00.

14. $13.20

Working: Cost of juice = 2 × $4.80 =$ 9.60. Cost of water = 3 × $1.20 =$ 3.60. Total = $9.60 +$ 3.60 = $13.20.
Teaching Note: Calculate the cost for each type of item separately, then add them together.
Common Mistake: Adding the prices first (4.80 + 1.20 = 6.00) and then multiplying by the total number of items (5 × 6.00 = 30.00) is incorrect because the items have different prices.

15. $47.52 (rounded to nearest cent)

Working: Discount = 15% of $55.90 = 0.15 ×$ 55.90 = $8.385 ≈$ 8.39 (rounded to nearest cent). Sale price = $55.90 -$ 8.39 = $47.51. Alternatively, sale price = 85% of$ 55.90 = 0.85 × $55.90 =$ 47.515 ≈ $47.52.
Teaching Note: A 15% discount means you pay 85% of the original price. Multiply the original price by 0.85. Round to the nearest cent.
Common Mistake: Forgetting to round to the nearest cent.

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

Each question carries 3 marks. 1 mark for correct method, 1 mark for correct working, 1 mark for correct answer.

16. $68.00

Working: Discount = 20% of $85 = 0.20 ×$ 85 = $17. Sale price =$ 85 - $17 =$ 68. Alternatively, sale price = 80% of $85 = 0.80 ×$ 85 = $68.
Teaching Note: A 20% discount means you pay 80% of the original price. Multiply the original price by 0.80.
Marking: 1 mark for finding the discount amount, 1 mark for subtracting correctly, 1 mark for correct answer.

17. $30.00

Working: Total cost = 120 × $0.45 =$ 54. Total revenue = 120 × $0.70 =$ 84. Profit = $84 -$ 54 = $30.
Teaching Note: Profit is the difference between revenue (money received) and cost (money spent). First find the total cost and total revenue, then subtract.
Marking: 1 mark for total cost, 1 mark for total revenue, 1 mark for correct profit.

18. $30.00

Working: Let the cost price be $x. Profit = 20% of x = 0.2x. Selling price = cost price + profit = x + 0.2x = 1.2x. Given selling price =$ 36, so 1.2x = 36. Therefore, x = 36 ÷ 1.2 = $30.
Teaching Note: If the profit is 20% of the cost price, then the selling price is 120% of the cost price. Divide the selling price by 1.2 to find the cost price.
Marking: 1 mark for setting up the equation, 1 mark for solving, 1 mark for correct answer.

19. $\frac{12}{25}$

Working: Total spending = $120 +$ 80 + $50 =$ 250. Fraction spent on food = $120 /$ 250 = 12/25 (simplified by dividing numerator and denominator by 10, then by 2 if needed: 120/250 = 12/25).
Teaching Note: A fraction compares a part to the whole. The part is the spending on food, and the whole is the total spending. Simplify the fraction by dividing the numerator and denominator by their greatest common factor (GCF). The GCF of 120 and 250 is 10, so 120/250 = 12/25.
Marking: 1 mark for total spending, 1 mark for correct fraction, 1 mark for simplification.

20. $112.50

Working: Discounted price = $150 - (10% of$ 150) = $150 -$ 15 = $135. Let the cost price be$ x. Profit = 20% of x = 0.2x. Selling price after discount = cost price + profit = x + 0.2x = 1.2x. Given selling price after discount = $135, so 1.2x = 135. Therefore, x = 135 ÷ 1.2 =$ 112.50.
Teaching Note: This is a two-step problem. First, find the selling price after the discount. Then, use the profit percentage to find the cost price. The profit is 20% of the cost price, so the selling price is 120% of the cost price.
Marking: 1 mark for finding the discounted price, 1 mark for setting up the equation, 1 mark for correct answer.
