Smt. Anagha Doshi purchased 22 shares of FV ₹ 100 for MV ₹ 660. After taking 20% dividend, she sold all shares at MV ₹ 650. She paid 0.1% brokerage for each trading. Find the percent of profit or loss (nearest integer). Also find the sum invested.

Answer: Sum invested = ₹ 14,534.52; profit of about 1%

Purchase: \( 22 \times 660 = ₹\,14{,}520 \); brokerage \( = 0.1\% = ₹\,14.52 \).

Sum invested \( = 14520 + 14.52 = ₹\,14{,}534.52 \)

Dividend \( = 22 \times (20\% \text{ of } 100) = 22 \times 20 = ₹\,440 \)

Sale: \( 22 \times 650 = ₹\,14{,}300 \); brokerage ₹ 14.30; received ₹ 14,285.70.

Total received \( = 14285.70 + 440 = ₹\,14{,}725.70 \)

Profit \( = 14725.70 - 14534.52 = ₹\,191.18 \)

\[ \text{Profit \%} = \frac{191.18}{14534.52} \times 100 \approx 1.3\% \approx 1\% \]
