All the three values related to profit and loss can be represented with help of these models.
Use the models by filling in the known values. It can help us decide how to find the missing value.
(a) CP = Rs. 950
SP = Rs. 1250
P/L = ?
Rs. 1250 – Rs. 950 = Rs. 300 profit
Subtract to find the difference
(b) SP = Rs. 796
L = Rs. 83
CP = Rs. ?
Rs. 796 + Rs. 83 = Rs. 879 Cost Price
Using model B
Add to find the sum
(c) CP = Rs. 1438
P = Rs. 415
SP = ?
Rs. 1438 + Rs. 415 = Rs. 1853 Selling Price
Using model A
