Question

A vendor bys lemons at Rs 25 per dozen and sells them at the rate 5 of for Rs 12. Find his gain Or loss per Cent

Answer 1

Solution :

            cost price  of 12 lemons ( in  Rupees) = 25

             therefore , cost price of one lemon(in Rupees) = 25 / 12

                 hence cost price of 5 lemons = 5*25/12

                                                             =125/12

                                                             =10.416

           Selling price of 5 lemons (in Rupees) =  12

           

Since the S.P of 5 lemons is more than C.P. hence the vendor has gain.

Therefore ,

Gain %  =  S.P - C.P/C.P*100

             =12 - 10.416/10.416*100

       Gain %     = 15.2.

Answer 2

It is given that a vendor buys lemon at rupees 25 per dozen.

So, 12 lemons cost ₹25

Therefore, 1 lemon would cost ₹25/12

Now,

SP of 5 lemons=₹12

So, SP of 1 lemon=₹12/5

So, here SP>CP, which means that there is a gain/profit.

Now, gain=SP-CP

=₹(12/5-25/12)

=₹19/60

Now, gain%=Gain/CP×100

=19/60/25/12×100

=76/5%

=15.2%
