Calculate Cost Price from Selling Price & Profit
This solution explains how to find the original cost price (CP) when the selling price (SP) and the profit percentage are known.
Identify Given Information
- Selling Price (SP) = ₹390
- Gain Percentage = 20%
Relevant Formula
The relationship between Selling Price (SP), Cost Price (CP), and Gain Percentage is given by the formula:
$ SP = CP \times \left(1 + \frac{Gain\%}{100}\right) $
Calculate Cost Price (CP)
To find the Cost Price, rearrange the formula:
$ CP = \frac{SP}{\left(1 + \frac{Gain\%}{100}\right)} $
Now, substitute the given values:
- $ CP = \frac{390}{\left(1 + \frac{20}{100}\right)} $
- $ CP = \frac{390}{\left(1 + 0.20\right)} $
- $ CP = \frac{390}{1.20} $
- $ CP = 325 $
Conclusion
Therefore, the Cost Price (CP) of the articles is ₹325.
