Question

a vendor buys lemons at rupees 25 per dozen and sell them at the rate of 5 for 12 rupees.find his gain or loss percent.

Answer 1

12 lemons = 25 rupees
1 lemon = 25/12
=2.0834 rupees
5 lemons = 2.0834 × 5= 10.47rupees
he sells 5 for 12
gain = 12-10.47= 1.53 rupees

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%
