Step 1: Calculate the dividend per share. Since the dividend is 9% of Rs. 25, we have: \[ \text{Dividend per share} = \frac{9}{100} \times 25 = 2.25. \] Step 2: The investment yields a 10% return on the purchase price, meaning the price at which the share is bought is: \[ \frac{2.25}{10\%} = \frac{2.25}{0.10} = 22.5. \] Thus, the purchase price of the share is Rs. 22.50.
