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\%.

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
