Question

a vendor buys lemon at rs 12 for for five lemons and sells them at rs 25 for 12 lemons find gain or loss percent

Answer 1

12*5 = 60 (take same no of Lemmon)
25*5= 125
P= 125-60
65
P%. 65/60*100
10.8%

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%
