Solution

1. Break Down the Problem

We are given the ratio of the shares of Adam, Tara, and Sophia as 2:5:14. We need to find out how much Sophia received given that Adam received £40.

2. Relevant Concepts

Let:

  • Adam's share = 2x
  • Tara's share = 5x
  • Sophia's share = 14x

From the problem, we know that Adam received £40, which corresponds to 2x.

3. Analysis and Detail

  1. Set up the equation based on Adam's share: 2x=40 2x = 40
  2. Solve for x x : x=402=20 x = \frac{40}{2} = 20
  3. Now calculate Sophia's share: Sophia’s share=14x=14×20=280 \text{Sophia's share} = 14x = 14 \times 20 = 280

4. Verify and Summarize

To ensure everything is correct, we can check the total ratio:

  • Adam: 2x=40 2x = 40
  • Tara: 5x=5×20=100 5x = 5 \times 20 = 100
  • Sophia: 14x=280 14x = 280

Total will be: 40+100+280=420 40 + 100 + 280 = 420 The ratios are 2:5:14 2:5:14 with total parts 2+5+14=21 2 + 5 + 14 = 21 . Each part represents:

  • Adam: 221×420=40\frac{2}{21} \times 420 = 40
  • Tara: 521×420=100\frac{5}{21} \times 420 = 100
  • Sophia: 1421×420=280\frac{14}{21} \times 420 = 280

Final Answer

Sophia received £280.
