Aman sells his goods at a certain price, 20% of which is profit. If the price at which he buys the goods increases by 10% and he sells them at a 9% higher price, then what will be his profit percentage?
Answer & explanation
Correct answer: option 2
Let SP = 100
20% of it is profit
SP Profit CP
100 20 80
+9% ↓ ↓ +10% P% = \(\frac{21}{88}\) × 100
109 88 = 23.8%
Diff 109 - 88 = 21
