Correct option is C
To calculate the price per share using the Walter Model, we apply the formula:

Where:
- P = Price per share
- D = Dividend per share = Payout Ratio × Earnings per Share
- r = Return on Investment (ROE) = 20%
- k = Cost of equity / Required rate of return = 16%
- E = Earnings per share = ₹4
Step 1: Calculate Dividend per share (D)
D = 40% of 4 = 0.4 × 4 = Rs. 1.60
Step 2: Substitute values into Walter’s formula

Therefore, the correct answer is Rs. 28.75
Information Booster:
Walter’s model shows how dividend policy affects the value of the firm based on the relationship between return on investment (r) and the cost of capital (k).
When r > k (as in this case, 20% > 16%), firm value increases if more earnings are retained rather than paid out as dividends.
The price increases as the company is effectively reinvesting earnings at a higher return than what shareholders require.
A lower payout ratio in this situation would result in even higher value per share under the Walter model.
