A shopkeeper sold two dolls at Rs.500 each. He sold one at 20% of loss and other at 20% profit. Find his profit or loss percentage.
Profit 5%
Profit 4%
Loss 5%
Loss 4%
Explanation:
In such problems where SP for two transactions is same as well as profit and loss percentages in both the transactions are same, you can use the formula
Loss % = (X/10)2 , where X = profit percentage = loss percentage
Therefore, Loss % = (X/10)2 = (20/10)2 = 400/100 = 4%
