Answer:
If the trader bought the TV set for Birr 2000 and sold it at a profit of 10%, the selling price can be calculated as follows:
Profit = 10% of the cost price = 10/100 * 2000 = Birr 200
Selling price = Cost price + Profit = 2000 + 200 = Birr 2200
Now, if the profit was a loss, we can use the same rate of 10% to calculate the selling price. In this case, the profit will be negative, indicating a loss.
Loss = 10% of the cost price = 10/100 * 2000 = Birr 200
Selling price = Cost price - Loss = 2000 - 200 = Birr 1800
Therefore, if the trader sold the TV set at a loss of 10%, the selling price would be Birr 1800.
