Detailed Solution
Download Solution PDFGiven:
A shopkeeper normally makes a profit of 20% in a certain transaction,
He weights 900 g instead of 1 kg, due to an issue with the weighing machine.
He charges 10% less than what he normally charges.
Formula used:
SP = \(\frac{100 - discount}{100}×CP\)
Calculations:
Let the cost price of 1 Kg of goods = Rs. 100
So, the selling price of 1 Kg of goods = 100 × 120/100 = Rs. 120
Cost price of 900 grams of goods = Rs. 90
According to question,
Shopkeeper charges 10% less what he normally charges
So, the new selling price = old selling price × (100 - 10)/100
⇒ New selling price = 120 × \(\frac{90}{100}\) =Rs. 108
So, profit = Rs. (108 - 90) = Rs. 18
So, profit % = (\(\frac{18}{90}\)) × 100 = 20%
Hence, Profit percentage is 20%.
