A shopkeeper sells his goods at the same price as what he pays his supplier. But when he buys from his supplier he takes 10% more than the indicated weight and when he sells, he gives a quantity, such that if 10% of that is added to it, the indicated weight is obtained. Find his profit percentage
Explanation:
Let CP = SP = 1/kg,
Shopkeeper buys 100 kgs from the supplier but he actually gets 10% more i.e., 110 kgs.
Now the shopkeeper will sell this 110 kgs but the indicated weight will be 110 + 10% of 110 = 121 kgs.
Total cost price = 1 × 100 = Rs. 100
Total selling price = 1 × 121 = Rs. 121
∴ Profit percentage = 21%.
Hence, option (d).
