Step 1: Understand the problem
Arbitrage means buying in one market at its opening price and simultaneously selling in another market at its opening price. To find the best arbitrage opportunity, we need to compare the relative prices of shares across BSE and NQE using the given exchange rate (#1 = Rs 11). The share with the maximum % profit difference is the answer.
Step 2: Compare SIFY
- Opening price on BSE = Rs 232
- Opening price on NQE = 21# = 21 × 11 = Rs 231
If bought on NQE (Rs 231) and sold on BSE (Rs 232), profit = 1.
% profit = (1 ÷ 231) × 100 ≈ 0.43%
Step 3: Compare INFY
- Opening price on BSE = Rs 105
- Opening price on NQE = 9.5# = 9.5 × 11 = Rs 104.5
If bought on NQE (Rs 104.5) and sold on BSE (Rs 105), profit = 0.5.
% profit = (0.5 ÷ 104.5) × 100 ≈ 0.48%
Step 4: Compare WIPRO
- Opening price on BSE = Rs 60
- Opening price on NQE = 5.5# = 5.5 × 11 = Rs 60.5
If bought on BSE (Rs 60) and sold on NQE (Rs 60.5), profit = 0.5.
% profit = (0.5 ÷ 60) × 100 ≈ 0.83%
Step 5: Compare TCS
- Opening price on BSE = Rs 450
- Opening price on NQE = 40.5# = 40.5 × 11 = Rs 445.5
If bought on NQE (Rs 445.5) and sold on BSE (Rs 450), profit = 4.5.
% profit = (4.5 ÷ 445.5) × 100 ≈ 1.01%
Step 6: Conclusion
The maximum % profit occurs in TCS when bought on NQE and sold on BSE, with a profit of about 1.01%.
Final Answer: The correct option is (D): TCS on NQE.
