Question

Krishna buy some oranges at the rate of 10 for Rs 200 and an equal number at 12 for Rs 300 he mixes both oranges together and sell them at 15 for Rs 450 find his profit percentage or loss percentage​

Answer 1

Answer:

Lets consider them both as oranges brand A and oranges brand B ...

brand A = 200 rupees , 10 oranges  , ie; 20 rupees each orange..

brand B = 300 rupees , 12 oranges ; ie ; 25 rupees each orange ...

Lets consider this third brand as AB brand ;

brand AB = 450 rupees , 15 oranges ; 30 rupees each orange....

First thing we have to know before finding profit or loss is that ;

we have to know is he selling oranges brand AB for the right price or not - ?

cost of brand AB =  A+B/[no.of oranges]

cost of brand A oranges = Rs.20 each orange

cost  of brand B oranges = Rs.25 each orange

AB brand = Rs.450 , 15 oranges ;

Therefore no.of oranges in brand AB = 15

so;  first we need to find out the ratio of brand A : brand B

=  10 : 12

= 5 : 6 [ simplest form ]

so ,

5 x 20 = 100 ; 6 x 25 = 150

100 + 150/15  ; Formula : brand A + brand B / [ no.of oranges ]

=  250/15

=  16.6 is the real cost of 1 orange .

but he sold them for 30 rupees each orange ; So he defintely made a great profit....

profit =  selling price - real price / real price x 100%

= 30 - 16.6 / 16.6 x 100 %

13.33/16.6x100%

= 79.64% is his profit percentage on oranges.
