When cost price is more than the selling price, there is a loss.

Loss = C. P. – S. P.

It is clear, if selling price is greater than cost price, profit will occur otherwise loss.

To find C. P., if S. P. and profit is given, we use
C. P. = S. P. – Profit

In case of loss, C. P. = S. P. + loss

To find S. P., if C. P. and profit is given, we use,

S. P. = C. P. + Profit

In case of loss, S. P. = C. P. – loss

Carry On

Say whether there is a loss or a profit :

Cost price = ` 245 Cost price = ` 595 Cost price = ` 435 Cost price = ` 305
Selling price = ` 280 Selling price = ` 559 Selling price = ` 495 Selling price = ` 210

Example : A shopkeeper bought a dictionary for ` 135.50 and sold it for
` 163.00. What is his profit and loss ?

Solution : Cost price (C. P.) = ` 135.50

Selling price (S. P.) = ` 163.00

Here, selling price is more than the cost price. So, there is a profit.

Profit = S. P. – C. P.

= 163.00 – 135.50 = ` 27.50

Shopkeeper made a profit of ` 27.50.

Example : A stamp collector bought a rare stamp for ` 14,890 and sold it at a profit
of ` 2,300. What was the selling price of the stamp ?

Solution : Cost price = ` 14,890

Profit = ` 2,300

S. P. = C. P. + profit

= ` 14,890 + ` 2,300
