22. Sarah is three years older than her brother Tom. The sum of their ages is 17. How old is Tom?
23. A farmer has 20 sheep and 15 cows. What is the ratio of sheep to cows?

Detailed Solutions and Explanations

Section 1: Number and Algebra

1. Following the order of operations (BODMAS/PEMDAS), the answer is: 9 + 20 - 5 = 24
2. Combine like terms: 3x - 2x + 5y + y = x + 6y
3. Subtract 7 from both sides: 2x = 8; Divide both sides by 2: x = 4
4. The factors of 12 are 1, 2, 3, 4, 6, 12. The factors of 18 are 1, 2, 3, 6, 9, 18. The highest common factor is 6.
5. 0.6 = 6/10 which simplifies to 3/5
6. The increase is 10 (60-50). The percentage increase is (10/50) x 100% = 20%

Section 2: Geometry and Measures

7. Area of a rectangle = length x width = 8cm x 5cm = 40cm²
8. Perimeter of a square = 4 x side length = 4 x 7cm = 28cm
9. Equilateral triangle
10. Volume of a cuboid = length x width x height
11. 1 kilometer = 1000 meters, so 5 kilometers = 5000 meters
12. The sum of interior angles in a hexagon is (6-2) x 180° = 720°. Each interior angle in a regular hexagon is 720° ÷ 6 = 120°.

Section 3: Ratio, Proportion, and Percentage

13. 15:25 simplifies to 3:5 (divide both sides by 5)
14. 3 apples cost £1.50, so 1 apple costs £0.50. 5 apples would cost 5 x £0.50 = £2.50
15. 25% of 80 = (25/100) x 80 = 20
16. 10% of £40 is £4. The new price is £40 - £4 = £36

Section 4: Statistics and Probability

17. Mean = (2 + 4 + 6 + 8 + 10) ÷ 5 = 6
18. The mode is the most frequent number, which is 3.
19. There are a total of 8 balls. The probability of picking a red ball is 5/8.
20. The probability of rolling a number greater than 4 (5 or 6) is 2/6 which simplifies to 1/3.

Section 5: Problem Solving

21. Speed = distance ÷ time = 120 miles ÷ 2 hours = 60 miles per hour
22. Let Tom's age be x. Sarah's age is x + 3. x + (x + 3) = 17; 2x + 3 = 17; 2x = 14; x = 7. Tom is 7 years old.
23. The ratio of sheep to cows is 20:15, which simplifies to 4:3.
