Answer: Profit of ₹ 1058.52
Number of shares \( = 10200 \div 100 = 102 \).
Brokerage on purchase \( = 0.1\% \text{ of } 10200 = ₹\,10.20 \); total cost \( = ₹\,10{,}210.20 \).
Sale of 60 shares at ₹ 125: \( 7500 - 0.1\% \text{ of } 7500 = 7500 - 7.50 = ₹\,7492.50 \)
Sale of 42 shares at ₹ 90: \( 3780 - 3.78 = ₹\,3776.22 \)
Total received \( = 7492.50 + 3776.22 = ₹\,11{,}268.72 \)
\[ \text{Profit} = 11268.72 - 10210.20 = ₹\,1058.52 \]
