A shopkeeper sold two items. The selling price of the first item equals the cost price of the second item. He sold the first item at a profit of 20% and the second item at a loss of 10%. What is his overall profit’ loss percent?
Explanation:
Let the cost price of first item = 100C
Profit on first item = 20%
Selling price of first item = 120100 × 100C = 120C
The selling price of the first item equals the cost price of the second item.
Cost price of the second item = 120C
Loss on second item = 10%
Selling price of second item = 90100 = 120C = 108C
Total cost price = 100C + 120C = 220C
Total selling price = 120C + 108C = 228C
Overall profit percentage = 228C-220C220C × 100
= 8C220C × 100
= 4011
= 3711%
Hence, the correct answer is Option A
