Percentage Discount
foundation tierProblem:
A shop reduces all prices by 15%. A jacket originally costs £240. What is the sale price?
Solution:
Find 15% of 240 = 36. Sale price = 240 − 36 = £204. Alternatively: 85% of 240 = 0.85 × 240 = £204.
Answer: £204
2Ratio Division

Ratio Division
foundation tierProblem:
Share £180 in the ratio 2:3:4.
Solution:
Total parts = 2 + 3 + 4 = 9. One part = 180 ÷ 9 = £20. Shares: £40, £60, £80.
Answer: £40, £60, £80
3Quadratic Equation
higher tier
Quadratic Equation
higher tierProblem:
Solve x² − 5x + 6 = 0
Solution:
Using the quadratic formula or factorising: (x − 2)(x − 3) = 0, so x = 2 or x = 3.
Answer: x = 2 or x = 3
4Compound Interest
higher tier
Compound Interest
higher tierProblem:
£5000 is invested at 3.5% compound interest per year. Calculate the value after 4 years.
Solution:
5000 × (1.035)⁴ = 5000 × 1.14752... = £5737.62 (to nearest penny)
Answer: £5737.62
5Trigonometry (Pythagoras)
higher tier
Trigonometry (Pythagoras)
higher tierProblem:
In a right-angled triangle, the hypotenuse is 13 cm and one side is 5 cm. Find the other side.
Solution:
Using Pythagoras: a² + 5² = 13². a² = 169 − 25 = 144. a = √144 = 12 cm.
Answer: 12 cm
