Well one way you can write it is 4x + 6y= 300 or you could simplify it and write it as y= -2/3x + 300, but I'm not quite sure how to write it a third way.

A garment dealer buys for Rs.10,000 and spend Rs.800 on freight. He seeks the entire stock for Rs.12,960. Find his loss/profit p
jeyben [28]

Answer:

Profit percentage=20\%.

Step-by-step explanation:

Given: A garment dealer buys goods for  \text{Rs.}\:10,000 and spend \text{Rs.}\:800 on freight. He seeks the entire stock for \text{Rs.}\:12,960.

To find:  His loss/profit percentage.

Solution:

We have,

Cost price of goods =\text{Rs.}\:10,000

Spent on freight =\text{Rs.}\:800

So, total cost of goods=\text{Rs.}\:10000+\text{Rs.}\:800=\text{Rs.}\:10,800

Selling price of entire stock =\text{Rs.}\: 12,960.

Now, Profit =\text{Selling price}-\text{Cost price}

So, Profit =\text{Rs.}\:12, 960-\text{Rs.}\:10,800=\text{Rs.}\:2160

Now,

\text{Profit\:\%}= \frac{\text{Profit}}{\text{Cost price}} \times 100\%

\implies\text{Profit\:\%}= \frac{2160}{\text{10,800}} \times 100\%

\implies\text{Profit\:\%}= \frac{2160}{108}\%

\implies\text{Profit\:\%}= 20\%

Hence, profit percentage =20\%.
