Question

a vendor buys lemons at rs 25 per dozen and sells them at the rate of 5 for rs 12. find his gain or loss per cent.

Answer 1

Hi ,

Cost price ( CP) of 1 dozen

lemons = Rs 25---( 1 )

Selling price of 5 lemons at the rate

of Rs12

Selling price of 12 lemons ( 1 dozen)

= ( 12 × 12 ) / 5

= Rs 28.80 ----( 2 )

Now , we know that

SP > CP

He gets profit or gain.

Profit ( g ) = SP - CP

=Rs 28.80 - Rs 25

= Rs 3.80

Profit percentage = ( gain × 100 )/CP

= ( 3.80 × 100 )/ 25

= 15.2%

The vendor gets 15.2% profit.

I hope this helps you.

:)

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%
