Understand the Net Asset Method.

The table lists the following equity components:

• Ordinary shares of 50 kobo each: 50
• Revaluation reserve: 80
• Retained profits: 145

The total value of the company using the net asset method is equal to its Total Equity.

$$\text{Total Equity} = \text{Ordinary shares} + \text{Revaluation reserve} + \text{Retained profits}$$ $$\text{Total Equity} = 50 + 80 + 145 = 275$$

The table also directly states "Total equity: 275".

The total value of the company using the net asset method is $\boxed{\text{275}}$.

The ordinary shares have a nominal value of 50 kobo each.
The total nominal value of ordinary shares is given as 50.
Since 1 kobo = N0.01, then 50 kobo = N0.50.

$$\text{Number of ordinary shares} = \frac{\text{Total nominal value of ordinary shares}}{\text{Nominal value per share}}$$ $$\text{Number of ordinary shares} = \frac{50}{0.50} = 100 \text{ shares}$$

The value of each share is calculated by dividing the Total Equity by the Number of ordinary shares.

$$\text{Value per share} = \frac{\text{Total Equity}}{\text{Number of ordinary shares}}$$ $$\text{Value per share} = \frac{275}{100} = 2.75$$

The value of each share of XYZ Limited is $\boxed{\text{2.75}}$.
