Example 3: Calculate the percentage of profit or loss in the following.
(a) S.P. = `600, C.P. = `540

(b) C.P. = `1000, S.P. = `900

Solution: (a) Here, S.P. = `600 and C.P. = `540

Since S.P. > C.P., there is a profit.

And Profit = S.P. – C.P. = `600 – `540 = `60
 Profit 
\ Profit% =  ×100  %
 CP 
..
 
 `60  1

=  × 100 % = 11 %
 `540  9

(b) Here, C.P. = `1000 and S.P. = `900

Since C.P. > S.P., there is a loss.

And Loss = C.P.– S.P. = `1000 – `900 = `100
 Loss 
\ Loss% =  ×100  %
 CP.. 
 

 `100 

=  × 100 % = 10%

 `1 000 
Also note that profit = Profit % of C.P. and loss =
loss% of C.P.

Example 4: A calculator is sold for `825 and the shopkeeper earns

a profit of `75. Find the profit percent.
Solution: Given, selling price of the calculator = `825 and profit = `75

Since profit percent is calculated on cost price, so first we
find it.

Cost price = Selling price – Profit
= `825 – `75 = `750
