1. Given profit or loss value Find cp or sp

2. We know that when there is Profit (P), Selling Price (SP)= Cost Price(CP) + Profit(P)
The other formulas derived from it are as follows
Profit(P) = Selling Price (SP)-Cost Price(CP)
Cost Price(CP) = Selling Price (SP) - Profit(P)
We know that when there is Loss(L), Selling Price (SP)= Cost Price(CP) - Loss(L)
The other formulas derived from it are as follows
Loss(L) = Cost Price(CP) - Selling Price (SP)
Cost Price(CP) = Selling Price (SP) + Loss(L)

3. Example 1 :- Selling price = Rs 5000 , profit =Rs 1500 , cost price = ?
Solution
