A person sold 100 shares of a stock at a loss of 40%.
selling price for the 100 shares was $3,000
Let the stock was bought at $x then we can write
![x-\frac{40x}{100}=3000\\ \\ \frac{100x-40x}{100}=3000\\ \\ \ \frac{60x}{100}=3000\\ \\ \ 60x= 3000*100\\ \\ x=\frac{3000*100}{60} \\ \\ \ x=5*100=5000\\](https://tex.z-dn.net/?f=%20x-%5Cfrac%7B40x%7D%7B100%7D%3D3000%5C%5C%20%5C%5C%20%5Cfrac%7B100x-40x%7D%7B100%7D%3D3000%5C%5C%20%5C%5C%20%5C%20%5Cfrac%7B60x%7D%7B100%7D%3D3000%5C%5C%20%5C%5C%20%5C%2060x%3D%203000%2A100%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B3000%2A100%7D%7B60%7D%20%5C%5C%20%5C%5C%20%5C%20x%3D5%2A100%3D5000%5C%5C%20)
Hence Amount paid for the Stock was $5000
