Calculating Actual Profit Percentage with Faulty Weight

This problem requires calculating the true percentage profit when a seller uses a faulty weight and states a loss on the cost price.

Understanding the Seller's Actions

  • The seller claims a 4% loss on the cost price (CP).
  • The seller uses a weight of 20g but measures it as 25g.

Step-by-Step Calculation

  1. Assume the cost price (CP) of 1 gram of flower is $c$.

    The intended weight is 25g. The cost price for 25g would be $25c$.

  2. The seller claims a 4% loss on the cost price. This means the selling price (SP) is calculated based on the cost of 25g.

    SP = CP of 25g - (4% of CP of 25g)

    SP = $25c - (0.04 \times 25c)$

    SP = $25c - 1c$

    SP = $24c$

  3. However, the seller only used 20g of weight. Therefore, the actual cost price incurred by the seller is the cost of 20g.

    Actual CP = Cost of 20g = $20c$

  4. Now, calculate the actual profit. Profit = Selling Price (SP) - Actual Cost Price (CP)

    Profit = $24c - 20c$

    Profit = $4c$

  5. Calculate the percentage profit based on the *actual* cost price.

    Percentage Profit = $(\frac{\text{Profit}}{\text{Actual CP}}) \times 100$

    Percentage Profit = $(\frac{4c}{20c}) \times 100$

    Percentage Profit = $(\frac{1}{5}) \times 100$

    Percentage Profit = $20\%$

Conclusion

By using a faulty weight (20g instead of 25g) while applying a 4% loss calculation based on the intended weight, the seller makes an actual profit of 20%.
