A book seller bought a book for Rs. 40 and sold it for Rs. 45. Find his gain percentage.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 12.5%.
Cost Price (CP) = ₹40
Selling Price (SP) = ₹45
Profit = SP − CP = 45 − 40 = ₹5
Gain % = (Profit/CP) × 100 = (40/5) × 100 = 12.5%
