Answer 1

Answer:

77.7 percent

Step-by-step explanation:

50 packets of milk bought on=50×28

=₹1400

sold them at price=50×36

=₹1800

percentage of profit=

$\frac{1400}{1800} \times100$

=77.7•/•

Answer 2

Answer :

$\sf { 28\dfrac{4}{7} \; \%}$ or 28.57%

Provided Information :

• A shopkeeper bought 50 packets of milk at Rs. 28 each.

• He sold them at Rs. 36 each.

To calculate :

• Percentage profit

Clarification :

As per the given question, we are provided with the cost price of each packet of milk, that is Rs. 28 and the selling price of each packet of milk, that is Rs. 36. We are asked to find out her percentage profit.

In order to calculate the percentage of profit, we need to find the total cost price and total selling price. After that, we'll calculate profit and then by using the formula to calculate total profit%, we'll calculate the required answer.

Explication of steps :

In order to find profit%, we need to calculate profit attained by her. For that, we need selling price and cost price.

Here, cost price of 1 packet of milk is Rs. 28. So, total cost price of 50 packets will be Rs. 28 times 50.

$\longrightarrow \sf {Cost \; price_{(50\; packets)} = Rs. \; \Big ( 50 \times 28 \Big )}$

After multiplying,

$\longrightarrow \sf {Cost \; price_{(50\; packets)} = Rs. \; 1400}$

Now, we need to find total selling price. Here, selling price of 1 packet of milk is Rs. 36. So, total selling price will be Rs. 36 times 50.

$\longrightarrow \sf {Selling \; price_{(50\; packets)} = Rs. \; \Big ( 50 \times 36 \Big )}$

After multiplying,

$\longrightarrow \sf {Selling \; price_{(50\; packets)} = Rs. \; 1800}$

Finding out profit using the formula.

$\longrightarrow \bf { Profit = S. P -C. P}$

Substituting values,

$\longrightarrow \sf { Profit = Rs. \; ( 1800 -1400)}$

Performing subtraction,

$\longrightarrow \bf \underline{ Profit = Rs. \; 400}$

Now, the last step we have to perform is to find profit% by using its formula.

$\longrightarrow \bf { Profit\% = \Bigg \{\dfrac{Profit}{C.P} \times 100 \Bigg \} \; \%}$

Now, substituting the values,

$\longrightarrow \sf { Profit\% = \Bigg \{\dfrac{400}{1400} \times 100 \Bigg \} \; \%}$

$\longrightarrow \sf { Profit\% = \Bigg \{\dfrac{400}{14} \Bigg \} \; \%}$

$\longrightarrow \sf { Profit\% = \Bigg \{\dfrac{200}{7} \Bigg \} \; \%}$

$\longrightarrow \sf { Profit\% = 28\dfrac{4}{7} \; \%}$

$\longrightarrow \bf \underline{ Profit\% =28.57\; \%}$

Therefore, profit percent is 28.57%.
