Anna makes cups. Each cup costs 6 Swiss francs to make. Anna puts the cups into boxes to sell. Each box contains 4 cups. Anna sells 80 boxes of cups for a total of 2160 Swiss francs.
(a) Work out the percentage profit Anna makes. Show your working clearly. (4)
The height of each cup is 9 cm, correct to the nearest cm.
(b) Write down the lower bound of the height. (1)
The weight of each cup is 120 g, correct to the nearest 10 g.
(c) Write down the upper bound of the weight. (1)
Show solution
Part (a)
- Number of cups = 80 × 4 = 320
- Cost of making them = 320 × 6 = 1920 Swiss francs
- Profit = selling price − cost = 2160 − 1920 = 240 Swiss francs
- Percentage profit = profitcost × 100 = 2401920 × 100
Answer: 12.5%
Part (b)
- Correct to the nearest cm means the true height is within half of 1 cm (0.5 cm) either side of 9.
Answer: 8.5 cm
Part (c)
- Correct to the nearest 10 g means the true weight is within half of 10 g (5 g) either side of 120.
Answer: 125 g
Nanette buys 60 notebooks for a total cost of 780 dirhams. Nanette sells 70% of the notebooks for 22 dirhams each. She sells the remaining notebooks for 19 dirhams each. Work out Nanette’s percentage profit. Give your answer correct to 3 significant figures.
Show solution
- 70% of 60 = 42 notebooks at 22 dirhams: 42 × 22 = 924 dirhams
- The remaining 60 − 42 = 18 notebooks at 19 dirhams: 18 × 19 = 342 dirhams
- Total income = 924 + 342 = 1266 dirhams, so profit = 1266 − 780 = 486 dirhams
- Percentage profit = profitoriginal cost × 100 = 486780 × 100 = 62.307…
Answer: 62.3%
Sarah makes and sells mugs. One day she makes 150 mugs. Her total cost for making these mugs is £1140. Of these mugs, 25 are small mugs, 32% are medium mugs and the rest are large mugs. Sarah sells small mugs for £8.50, medium mugs for £11.20 and large mugs for £14.20. Sarah sells all 150 mugs. Work out her percentage profit. Give your answer correct to the nearest whole number.
Show solution
- Small: 25 × 150 = 60. Medium: 32% of 150 = 48. Large: 150 − 60 − 48 = 42.
- Income: 60 × 8.50 = £510, 48 × 11.20 = £537.60, 42 × 14.20 = £596.40. Total = £1644
- Profit = 1644 − 1140 = £504
- Percentage profit = 5041140 × 100 = 44.2…
Answer: 44%

Express the percentage of students studying Italian or Spanish as a percentage of those studying French or German.
Show solution
- German: 45% of 180 = 0.45 × 180 = 81 students
- French or German: 15 + 81 = 96 students
- Italian or Spanish: 180 − 96 = 84 students
- As a percentage of French or German: 8496 × 100
Answer: 87.5%
Divya and Yuan each pay for a holiday at a special offer price. Divya’s holiday: normal price 1600, special offer 16% off the normal price. Yuan’s holiday: normal price 1400, special offer k% off the normal price. The amount that Divya pays is the same as the amount that Yuan pays. Work out the value of k.
Show solution
- Divya pays 84% of 1600: 1600 × 0.84 = 1344
- Yuan pays 1344 out of 1400: 13441400 = 0.96 = 96%
- So Yuan’s discount is 100% − 96% = 4%
Answer: k = 4
Ava records the number of kilometres she drives each month. In April, Ava drove 943 kilometres. This is 15% more than the number of kilometres she drove in March. Work out the number of kilometres Ava drove in March.
Show solution
- March is the original amount (100%). April is 15% more, so April is 100% + 15% = 115% of March.
- 115% as a multiplier is 1.15, so March × 1.15 = 943
- To undo the increase, divide by the multiplier: 943 ÷ 1.15
Answer: 820 kilometres

Slavomir invests 5200 euros in a savings account for 4 years. He gets 2.5% per year compound interest. Work out how much money Slavomir will have in the savings account at the end of 4 years. Give your answer correct to the nearest euro.
Show solution
- Each year the amount is multiplied by 100% + 2.5% = 102.5%, which is a multiplier of 1.025.
- Compound interest over 4 years means multiplying by 1.025 four times: 5200 × 1.0254
- 5200 × 1.0254 = 5739.82…
- Round to the nearest euro.
Answer: 5740 euros
In a sale, normal prices are reduced by 28%. The sale price of a watch is 198 euros. Work out the normal price of the watch.
Show solution
- The normal price is 100%. After a 28% reduction the sale price is 100% − 28% = 72% of the normal price.
- So normal price × 0.72 = 198
- Normal price = 198 ÷ 0.72
Answer: 275 euros
Asha bought an apartment. The table gives information about the value of apartments, in euros, and the annual service charge band.

Pam bought a boat. In each year after Pam bought the boat, the value of the boat depreciated by 15%.
(b) Work out the total percentage by which the value of the boat had depreciated by the end of the second year after Pam bought the boat. (3)
Show solution
Part (a)
- The 2021 value is 104% of the 2020 value, so the 2020 value = 634 400 ÷ 1.04 = 610 000 euros
- 610 000 is in band B (600 000 ≤ x < 700 000), and 634 400 is also in band B.
Answer: No, it is band B in both years
Part (b)
- Each year the value is multiplied by 0.85 (100% − 15%).
- After two years: 0.85 × 0.85 = 0.7225, so the boat is worth 72.25% of its original value.
- Total depreciation = 100% − 72.25%
Answer: 27.75%

Jonty has a storage container in the shape of a cuboid 12 m long, 2.5 m wide and 3 m high. Jonty is going to paint the outside of his storage container, apart from the base. He needs enough paint to cover the four sides and the top. Each tin of paint covers an area of 15 m2. The cost of each tin of paint recently increased by 10%. After the increase, the cost of each tin of paint is £26.95. Jonty says “Before the increase, I could have bought enough paint for less than £200″. Show that Jonty is correct. Show your working clearly.
Show solution
- Area to paint: top 12 × 2.5 = 30 m2; two long sides 2 × 12 × 3 = 72 m2; two ends 2 × 2.5 × 3 = 15 m2. Total = 117 m2
- Tins needed = 117 ÷ 15 = 7.8, so he needs 8 tins.
- Price before the 10% increase: 26.95 ÷ 1.1 = £24.50
- Cost of 8 tins before the increase = 8 × 24.50 = £196
Answer: £196 < £200, so Jonty is correct

Himari invests 200 000 yen for 3 years in a savings account paying compound interest. The rate of interest is 1.8% for the first year and x% for each of the second year and the third year. The value of the investment at the end of the third year is 209 754 yen. Work out the value of x. Give your answer correct to one decimal place.
Show solution
- After year 1: 200 000 × 1.018 = 203 600 yen
- The same multiplier m is used for years 2 and 3: 203 600 × m2 = 209 754, so m2 = 1.030 22…
- m = √1.030 22… = 1.015
- A multiplier of 1.015 is 1.5% interest.
Answer: x = 1.5
Zhou invests some money for 2 years. He invests 2500 with Bank A, where amount of money invested : total amount of interest after 2 years = 20 : 3. He invests 3000 with Bank B at 4% per year compound interest for 2 years. Zhou receives more interest from Bank A than from Bank B. How much more?
Show solution
- Bank A: the ratio 20 : 3 means the interest is 320 of the amount invested: 320 × 2500 = $375
- Bank B: value after 2 years = 3000 × 1.042 = 3000 × 1.0816 = $3244.80
- Bank B interest = 3244.80 − 3000 = $244.80
- Difference = 375 − 244.80
