Explanation:

- Let's assume the number of fruits bought at each rate is x.

- Cost of fruits bought at 11 for Rs100:

- Total fruits = x

- Cost = x/11 * 100 = 100x/11 Rs

- Cost of fruits bought at 9 for Rs100:

- Total fruits = x

- Cost = x/9 * 100 = 100x/9 Rs

- Total cost of all fruits:

- Total cost = 100x/11 + 100x/9

- Total cost = (900x + 1100x)/99 = 2000x/99 Rs

- Total fruits:

- Total fruits = 2x (since equal number are bought)

- Selling price of all fruits:

- Sold at 10 for Rs100

- SP = (2x/10) * 100 = 20x Rs

- Profit/Loss Calculation:

- Profit/Loss = Selling Price - Cost Price

- = 20x - 2000x/99

- = (1980x - 2000x) / 99

- = -20x/99

- Loss percent:

- Loss% = (Loss/Cost Price) * 100

- = (-20x/99) / (2000x/99) * 100

- = -1%

Option:4 - Loss, 1%
