Question

A vendor buys lemons at Rs 25 per dozen and sells them at the rate of 5 for Rs 12. Find his loss or gain percentage.

Answer 1

he sells 5 for Rs 12 then 12 for 28.8 by unitary method and profit =28.8-25=Rs 3.8
therefore
profit%=3.80÷25×100
profit%=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%
