Correct Answer - Option 3 : 25%
Given:
Selling price = cost price – 25% of cost price
Calculation:
Let the cost price for 1000 gram = Rs. 1000
Selling price of 1000 gram = Rs. 750
But, due to false weighing
Selling price of 600 gram = Rs. 750
Cost price of 600 gram = Rs. 600
So, there is a profit
Profit = Rs. 750 – Rs. 600
⇒ Rs. 150
Profit% = [(150/600) × 100]%
⇒ 25%
