Percentage, Profit and Loss 113

Let’s Attempt

Example 1: Ronit bought a bicycle for ` 3000 and sold it for ` 2700. Find his profit or loss.

Solution: Cost price of bicycle = ` 3000

Selling price of bicycle = ` 2700
Since, C.P. > S.P., he suffers loss.

Loss = 3000 – 2700 = ` 300

Example 2: Smita bought 50 kg of onions for ` 500. If she sold the onions at ` 12 per kg, what
was her profit?

Solution: Cost price of 50 kg onions = ` 500

Selling price of 50 kg onions = ` 12 × 50 = ` 600
Since, S.P. > C.P., she earns profit

Profit = S.P. – C.P. = ` 600 – 500 = ` 100

Example 3: Raju bought a pen for ` 55. He sold it at a loss of ` 12. What was the selling
price of the pen?
Solution: Here, C.P. = ` 55 and Loss = ` 12

Thus, S.P. = C.P. – Loss = ` 55 – ` 12 = ` 43

The selling price of pen was ` 43.

Example 4: Find the cost price of an article which is sold for ` 550 at a loss of ` 15.

Solution: Here, S.P. = ` 550 and loss = ` 15
Now, C.P. = S.P. + Loss = ` 550 + ` 15 = ` 565

The cost price of article is ` 565

Example 5: A man buys pen at cost of ` 10 each and sell then ` 11.50 each. Find his profit per
cent on each pen.
Solution: C.P. of each pen = ` 10

S.P. of each pen = ` 11.50

\ Profit = ` 11.50 – ` 10 = ` 1.50

Now, profit % = Profit ×100%
C.P.

150.
= × 100%
10

= 15%

Thus, the man earns a profit of 15% on selling each pen.
