Final answer:
The cost price of one glass that Parwati brought, after accounting for the 20% profit included in the selling price of Rs. 25, was approximately Rs. 20.83.
Step-by-step explanation:
The question asks to find the cost price of one glass that Parwati brought, given that she sold the remaining glasses at a profit. Since 20 glasses were broken out of 60, Parwati was left with 40 glasses to sell. To find the cost price, we need to first determine the selling price at which Parwati makes a 20% profit.She sold each glass at Rs. 25. The 20% profit is included in the Rs. 25, making it 120% of the cost price. Therefore, to find the original cost price (100%), we need to divide the selling price (Rs. 25) by 120% (or 1.2).
Cost price per glass = Rs. 25 / 1.2 = Rs. 20.83 (rounded to two decimal places)Thus, the cost price of one glass was approximately Rs. 20.83.To find the cost price of one glass, we need to determine the total cost of all the glasses purchased by Parwati. Since 20 glasses were broken and she sold the remaining glasses at a 20% profit, we can set up the following equation:
