Question

A shoperkeeper buys 15 oranges for 21 rupees and selles them at 20 oranges for 21 rupees find the gain or losss percentage

Answer 1

Step-by-step explanation:

SP of 12 oranges is = Rs. 60

Loss = 25%

CP of 12 oranges is = 60×10075=80

to gain 25%

SP = 80+25100×80 = Rs. 100

12 oranges sell for Rs. 100 to gain 25% = 12 Oranges

Answer 2

$\huge \fbox{ \underline \purple{Answer }}$

Let us write in detail about the given information

BUYING DETAILS ;

No of oranges brought by him = 15

Rate at which he had brought = Rs. 21

Then,

Cost of 1 orange = $\frac{Total cost }{No of oranges }$  = $\frac{21}{15}$  = $Rs 1.4$

SELLING DETAILS :

No of oranges sold by him = 20

Rate at which he had sold = Rs. 21

Then,

Cost of 1 orange = $\frac{Total cost }{No of oranges }$ = $\frac{25}{20}$ = $Rs 1.25$

Since cost price of 1 orange is greater the selling price of 1 orange is has lost

C.P > S.P = Loss

So Let us calculate Loss %

Loss = Cost price - Selling Price

        = 1.40 - 1.25

        =   0.15

Then,

Loss %  =  $\frac{Loss }{C.P} * 100$

            =  $\frac{0.15}{1.4} * 100$

            =  $\frac{15}{1.4}$

            $= 10.71 %$ %

Hence, there is loss of 10.71%.

To find gain or loss of the any given question follow these steps

Solve with given quantities and find whether C.P > S.P or S.P > C.P

If C.P is greater then there is Loss

If S.P is greater then there is Gain

Then According you can  use and calculate Gain or Loss %

To find Loss { Loss = C.P - S.P }

To find Gain { Gain = S.P - C.P }
