A shopkeeper purchase 18 dozen of eggs at the rate of 50 per dozen. He sold the eggs at the
rate of 25.50 each. Find his profit or loss and profit or loss percent.​

Answer 1

Step-by-step explanation:

Given:-

CP = 18 dozens at ₹ 50 per dozen.

SP = 18 dozens at ₹ 5.5 each egg.

To Prove:-

Loss or gain for the shopkeeper

Solution :-

★ A Shop keeper purchased 18 dozen eggs at ₹50 per dozen.

CP = Number * Rate

CP = ₹(18*50)

CP = ₹900

Now,

The Shopkeeper sold 18 dozens of eggs at ₹5.5 each.

\bold{ \red{1 \: Dozen = 12 \: each}{} }{}1Dozen=12each

=> Number of eggs = 18*12

★Number of eggs = 216

\begin{gathered}\bold{ \red{★Selling \: price = Number \times Rate}{} }{} \\ \\ SP = ₹(216 \times 5.5) = ₹ \: 1188\end{gathered}

★Sellingprice=Number×Rate

SP=₹(216×5.5)=₹1188

As by,

1188 > 900 = SP > CP

So, Its Profit.

The profit rate = 1188-900 = 288

Let us find the profit % = Profit/CP *100

Profit % = 288/900*100

Profit %= 32%

★ The profit = ₹288

★. The profit % = 32%

Answer 2

Answer:

It is given that

C.P. of one dozen eggs =12 eggs = Rs. 18

Profit =15%

We know that

S.P. of 12 eggs =[1+50/100] of Rs.18

It can be written as

=(150/100×18)

By further calculation

= (3/2 × 18)

So we get

=3×9

=Rs.27

S.P. of 1 egg =Rs.27/12

So we get

=Rs.9/4

=Rs.2.25
