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 $=20\%$ .

The length of a rectangle is one inch less than three times its width. If the perimeter of the rectangle is 118 inches, find the

IgorLugansk [536]

We can set up the width a X and, from the description the length would be 3X-1. The perimeter of a rectangle is determined by 2XL + 2Xw. Plugging into the equation 2(3X-1) + 2(X) = 118. Next distribute to get 6X-2 + 2X = 118. Combine like terms to get 8X = 120. Divide by 8 to get X = 15. The width is 15. The length is 3(15)-1 or 44. 88 +30 = 118
