Question

A fruit seller purchase apple at the rate of rupees 20 per dozen for rupees 56 and sold them at the rate of rupees 35 per dozen .find out his gain or loss percent .

Answer 1

Answer:

Let the number of oranges bought = LCM of 20 and 12=60. ∵ he sold in dozens i.e, in multiples of 12

C.P. of 20 oranges = Rs.56

∴ C.P. of 1 orange = Rs.

20

56

Hence the C.P. of 60 oranges = Rs.(

20

56

×60)= Rs. 168

S.P. of 12 oranges = Rs. 35

∴ S.P. of 1 orange = Rs.

12

35

Hence, the S.P. of 60 oranges = (

12

35

×60)=Rs.175

Thus C.P. = Rs.168 and S.P. = Rs. 175

Since (S.P.) > (C.P.) So, the vendor has made a gain

Gain =(175−168)= Rs. 7

∴ Gain % = (

C.P.

Gain

×100)%=(

168

7

×100)%=

6

25

%

We can see that, p=25 and q=6 and both are coprimes

Thus, p−q=25−6=19
