1. Find profit and loss

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. 90 120 Profit Profit=SP-CP=120-90-30
Find the Profit/loss value
Cost Price Selling Price Profit/Loss Profit/Loss value
(CP) (SP) (P/L)
Profit Profit=SP-CP=
Loss Loss=CP-SP= =21
Loss Loss=CP-SP= =51
Profit Profit=SP-CP=99-75=14

4. Example 1:
If the cost price of a bag is Rs 575 and the selling price is Rs Find profit/loss value.
Solution
Given: Cost Price=Rs 575, Selling Price=Rs 625
To find: Profit/Loss value
Since Selling Price>Cost Price, there is profit.
We know that Profit=Selling Price-Cost Price.
∴ Profit= =50
Ans: Profit = Rs 50

5. Example 2:
If the cost price of the box is Rs 155 and the selling price is Rs 140. Find profit/loss value.
Solution
Given: Cost Price=Rs 155, Selling Price=Rs 140
To Find: Profit/Loss value
Since Selling Price<Cost Price, there is Loss
We know that Loss=Cost Price-Selling Price.
∴ Loss= =15
Ans: Loss = Rs 15

6. Example3:
A vegetable seller bought 40 kg onion Rs 480. First 35 kg he sold them for Rs 20.Remaining he
sold them for Rs 15.Find the profit or loss value
Solution
Given : Cost Price=Rs 480,
Selling price= Rs 20 per kg for first 35kg and Rs 15 per kg for the remaining.
To find: profit or loss value
First calculate total selling price
Selling price for first 35kg= 20 x 35 = (∵ price per kg=20 for 35kg)
After selling 35kg onion seller will have 40-35=5 kg remaining
Selling price for remaining 5kg=15 x 5=75 (∵ price per kg=15 for remaining 5kg)
Total selling price=700+75=775

7. Example 3 (Continue)
Total selling price=775
Since Selling Price>Cost Price , there is profit
We know that Profit=Selling Price-Cost Price.
∴ Profit= =295
Ans: Profit = Rs 295

8. Try these
