Question

A vendor buys lemons at rupees 25 per dozen and sells them at rate of 5 for rupees 12.f ind his gain% or loss%

Answer 1

Vendor's total cost price = 25×12= 300
Vendor's total selling price = 5×12=60
Loss percentage = 300/60×100%=500%

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%
