Here is the breakdown of the problem and its solution:

Problem Setup:

• Number of shares: $40$
• Purchase price per share: $30$
• Dividend per share: $1$
• Sale price per share: $67$

We need to calculate the following:

(a) Total Purchase Price:

$\text{Total Purchase Price} = \text{Number of Shares} \times \text{Purchase Price per Share}$ $\text{Total Purchase Price} = 40 \times 30 = 1200$

(b) Total Dividend Amount:

$\text{Total Dividend Amount} = \text{Number of Shares} \times \text{Dividend per Share}$ $\text{Total Dividend Amount} = 40 \times 1 = 40$

(c) Capital Gain or Loss:

$\text{Capital Gain or Loss} = (\text{Sale Price per Share} - \text{Purchase Price per Share}) \times \text{Number of Shares}$ $\text{Capital Gain or Loss} = (67 - 30) \times 40 = 37 \times 40 = 1480$

(d) Total Return on Investment:

$\text{Total Return} = \text{Capital Gain or Loss} + \text{Total Dividend Amount}$ $\text{Total Return} = 1480 + 40 = 1520$

(e) Percentage Return:

$\text{Percentage Return} = \left( \frac{\text{Total Return}}{\text{Total Purchase Price}} \right) \times 100$ $\text{Percentage Return} = \left( \frac{1520}{1200} \right) \times 100 = 1.2667 \times 100 \approx 127\%$

Final Answers:

1. (a) Total Purchase Price: $1200$
2. (b) Total Dividend Amount: $40$
3. (c) Capital Gain or Loss: $1480$
4. (d) Total Return: $1520$
5. (e) Percentage Return: $127\%$
