Question

question: A vendor buys lemons at rs.25 per dozen and sells them at the rate of 5 for rs.12. Find his gain or loss percent.

Answer 1

cp of one lemon=25/12
sp of one lemon=12/5
25/12  12/5
lcm=60
125/60     144/60
profit=144/60 - 125/60
        =19/60
p%=19/60 divided by 25/12 *100
     =76/5=15.4%

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%
