Official examination question with verified M1/A1 mark scheme and step-by-step mathematical reasoning.

Problem Statement

A man invests $₹9,600$ on $₹100$ shares at $₹80$. If the company pays him $18\%$ dividend, find: (i) The number of shares he buys. (ii) His annual dividend income. (iii) The percentage return on his investment.

Verified Solution & Marking Scheme

Number of Shares
$\text{Number of shares} = \frac{\text{Total Investment}}{\text{Market Value of 1 share}} = \frac{9600}{80} = 120 \text{ shares}$
Annual Dividend Income
$\text{Face Value (FV) of 120 shares} = 120 \times 100 = ₹12,000$ $\text{Annual Income} = 18\% \text{ of } 12000 = \frac{18}{100} \times 12000 = ₹2,160$
Percentage Return on Investment
$\text{Return \%} = \frac{\text{Annual Income}}{\text{Total Investment}} \times 100 = \frac{2160}{9600} \times 100 = \frac{216}{96} \times 10 = 22.5\%$
