Question: I bought 200 shares of a company at ₹150 each. The company later issued bonus shares in a 1:2 ratio (1 additional share for every 2 held). If I now sell all my shares at ₹180 each, what is my revised average cost per share after the bonus issue, and what is my total capital gain?
Answer: Revised average cost per share ≈ ₹100. Total capital gain ≈ ₹24,000.
