Answer: A

To find the profit made by the investor, we first determine the number of shares purchased for each stock and then calculate the total selling value.

1. Initial Investment and Shares Purchased:

  • Stock A:
    • Price per share = Rs. 50\text{Rs. } 50
    • Amount invested = Rs. 100\text{Rs. } 100
    • Number of shares purchased = 10050=2\frac{100}{50} = 2 shares
  • Stock B:
    • Price per share = Rs. 80\text{Rs. } 80
    • Amount invested = Rs. 80\text{Rs. } 80
    • Number of shares purchased = 8080=1\frac{80}{80} = 1 share

Total initial investment = Rs. 100+Rs. 80=Rs. 180\text{Rs. } 100 + \text{Rs. } 80 = \text{Rs. } 180.

2. Selling Value the Next Day:

  • Stock A:
    • New price per share = Rs. 55\text{Rs. } 55
    • Selling value of 22 shares = 2×55=Rs. 1102 \times 55 = \text{Rs. } 110
  • Stock B:
    • New price per share = Rs. 70\text{Rs. } 70
    • Selling value of 11 share = 1×70=Rs. 701 \times 70 = \text{Rs. } 70

Total selling value = Rs. 110+Rs. 70=Rs. 180\text{Rs. } 110 + \text{Rs. } 70 = \text{Rs. } 180.

3. Profit Calculation:

Profit=Total Selling Value−Total Investment\text{Profit} = \text{Total Selling Value} - \text{Total Investment}Profit=180−180=Rs. 0\text{Profit} = 180 - 180 = \text{Rs. } 0

Therefore, the profit made by the investor is Rs. 0 (Option A).
