1. Find selling price or cost price

2. Finding Cost Price( CP), if Selling Price( SP) and Profit(P) or Loss(L) is provided
If Selling Price and Loss is given CP = SP + Loss
If Selling Price and Profit is give CP = SP - Profit
Finding Selling Price( SP), if Cost Price( CP) and Profit(P) or Loss(L) is provided
If Cost Price and Loss is given SP = CP ̶ Loss
If Cost Price and Profit is give SP = CP + Profit

3. To Remember To Find SP To Find CP SP = CP + Profit CP = SP + Loss
SP = CP ̶ Loss
To Find CP
CP = SP + Loss
CP = SP ̶ Profit

4. Given:- Profit (p)=150 , Selling price(SP)=480
Example 1: Find Cost price when Profit is Rs 150 and Selling price is Rs 480
Solution
Given:- Profit (p)=150 , Selling price(SP)=480
To Find:- Cost price
Cost price(CP) = Selling Price(SP) ̶ Profit(P)
CP = ̶
CP = = 230
Ans :- Cost price(CP) = Rs 230
To Find CP
CP = SP + Loss
CP = SP ̶ Profit

5. Given:- Profit (P)=230 , Cost price(CP)=480
Example 2: Find Selling price when Profit is Rs 230 and Cost price is Rs 480
Solution
Given:- Profit (P)=230 , Cost price(CP)=480
To Find:- Selling price
Selling Price (SP) = Cost Price(CP) + Profit(P)
230 =
SP = = 710
Ans :- Selling price(SP) = Rs 710
To Find SP
SP = CP + Profit
SP = CP ̶ Loss

6. Given:- Loss (L) = 95 , Selling price(SP) = 320
Example 3: Find Cost price when Loss is Rs 95 and Selling price is Rs 320
Solution
Given:- Loss (L) = 95 , Selling price(SP) = 320
To Find:- Cost price
Cost Price(CP) = Selling Price(SP) + Loss (L)
CP =
CP = = 415
Ans :- Cost price(CP) = Rs 415
To Find CP
CP = SP + Loss
CP = SP ̶ Profit

7. Given:- Loss(L) = 240 , Cost price(CP)=725
Example 4: Find Selling price when Loss is Rs 240 and Cost price is Rs 725
Solution
Given:- Loss(L) = 240 , Cost price(CP)=725
To Find:- Selling price
Selling price(SP) = Cost Price(CP) ̶ Loss (L)
SP = ̶
SP = = 485
Ans :- Selling price (SP) = Rs 485
To Find SP
SP = CP + Profit
SP = CP ̶ Loss
