Question

A vendor buys a lemons at rs 25 per dozen and sells at 5 for rs 12.his gain percent is

Answer 1

25 per dozen means about 25/12≈Rs. 2.083 per one lemon. Five for Rs.12 means 12/5=Rs. 2.4 per lemon.

Sales Price is greater, and thus the process results in a profit.
Profit is 2.4-2.083=0.317.
Profit percentage is 0.317/2.083×100≈15.55

Ans≈15.55%

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%
