Calculating Percentage Loss on Sale

Let's break down how to calculate the percentage of loss Dipali incurred when selling the set of cups.

Understanding Cost Price and Selling Price

  • Cost Price (CP): This is the original price at which Dipali bought the set of cups. In this case, CP = Rs. 375.
  • Selling Price (SP): This is the price at which Dipali sold the set of cups. Here, SP = Rs. 345.

Identifying Loss or Profit

When the Selling Price is less than the Cost Price, it is a case of loss. If the Selling Price is greater than the Cost Price, it is a profit.

In this problem, SP (Rs. 345) < CP (Rs. 375), so Dipali incurred a loss.

Calculating the Amount of Loss

The amount of loss is the difference between the Cost Price and the Selling Price.

Loss = Cost Price - Selling Price

Loss = Rs. 375 - Rs. 345

Loss = Rs. 30

Dipali incurred a loss of Rs. 30.

Calculating the Percentage Loss

Percentage loss is calculated with respect to the Cost Price. The formula for percentage loss is:

\(\text{Percentage Loss} = \left( \frac{\text{Loss}}{\text{Cost Price}} \right) \times 100\%\)

Now, let's plug in the values:

\(\text{Percentage Loss} = \left( \frac{30}{375} \right) \times 100\%\)

To simplify the fraction \(\frac{30}{375}\):

  • Both 30 and 375 are divisible by 5: \(\frac{30 \div 5}{375 \div 5} = \frac{6}{75}\)
  • Both 6 and 75 are divisible by 3: \(\frac{6 \div 3}{75 \div 3} = \frac{2}{25}\)

So, the percentage loss calculation becomes:

\(\text{Percentage Loss} = \left( \frac{2}{25} \right) \times 100\%\)

\(\text{Percentage Loss} = \frac{2 \times 100}{25}\%\)

\(\text{Percentage Loss} = 2 \times \frac{100}{25}\%\)

\(\text{Percentage Loss} = 2 \times 4\%\)

\(\text{Percentage Loss} = 8\%\)

The percentage of loss Dipali incurred is 8%.

Percentage Loss \(\left( \frac{\text{Loss}}{\text{CP}} \right) \times 100\%\) When there is a loss
Percentage Profit \(\left( \frac{\text{Profit}}{\text{CP}} \right) \times 100\%\) When there is a profit

Additional Information on Loss and Profit

Understanding loss and profit is fundamental in business and everyday finance. Here are a few key points:

  • Loss and profit are always calculated based on the Cost Price unless otherwise specified.
  • A loss occurs when the money received from selling something is less than the money spent to acquire it.
  • A profit occurs when the money received from selling something is more than the money spent to acquire it.
  • Knowing how to calculate percentage loss or profit helps in comparing the performance of different sales or investments.
  • In this scenario, Dipali had to sell the cups at a loss, possibly due to clearing old stocks, as mentioned in the question. Businesses sometimes do this to free up space or capital, even if it means a loss on specific items.
