Answer:
gain = 0
% = 0
Step-by-step explanation:
<em><u>Profit</u></em>
He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%
₹1500 * 125/100 = ₹187500/100 = ₹1875
<em><u>Loss</u></em>
Here he sells it for 25% less than the selling price he wanted.
100% - 25% = 75%
₹1500 * 75/100 = ₹112500/100 = ₹1125
<em><u>Discussion</u></em>
He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.
What he actually accomplishes is ₹1125 + ₹1875 = ₹3000
So he has a net gain (loss) of 0.
The % is 0
