A shopkeeper claims to sell his articles at 20 per kg which cost him 23 per kg. But while selling, he uses a false weight and gives only 800 gm instead of 1 kg. What is his profit percentage?
Sol:
Shopkeeper claims to sell at Rs. 20 per kg,
He buys it for Rs. 23 per kg Actual weight he sells at Rs. 20 is 800g.
Calculations:
⇒ Selling price of 800 gm article = Rs. 20
∴ Selling price of 1 kg article = 20 × (1000/800) = Rs. 25
⇒ Cost price of 1 kg article = Rs 23
