Show answer and explanation

Correct answer: (A) 0

Explanation

Stock A costs Rs. 50 per unit, so Rs. 100 buys 2 units. Selling them at Rs. 55 each gives Rs. 110, which is a profit of Rs. 10. Stock B costs Rs. 80 per unit, so Rs. 80 buys 1 unit. Selling it at Rs. 70 gives Rs. 70, which is a loss of Rs. 10. The net profit is therefore Rs. 10 - Rs. 10 = 0. Hence, option (A) is correct.
