A shopkeeper bought 100 pens at Rs 10 each. He sold 60 pens at 20% profit and the rest at 10% loss.
What is the overall profit or loss percentage?
Show answer & explanation
Correct answer: D
Explanation
Total Cost Price = 100 × 10 = 1000
Selling Price of 60 pens = 60 × (10 + 20% of 10) = 60 × 12 = 720
Selling Price of 40 pens = 40 × (10 − 10% of 10) = 40 × 9 = 360
Total Selling Price = 720 + 360 = 1080
Profit = 1080 − 1000 = 80
Profit % = (80 / 1000) × 100 = 8%
