A pair of shoes which costs Rs 320 was sold at a loss of 5%what was the selling price if it is sold at profit of 20%find the gai

taurus [48]

Answer:

The Sell Price of the shoe at 5% loss is Rs 304.

The Sell Price of the shoe at 20% profit is Rs 384.

The Total Gain Percent is 12.5% when shoes are sold at Rs.360.

Step-by-step explanation:

Given,

Cost Price(C.P.) of shoe = Rs 320

Case 1.

Loss = 5%

C.P. = Rs 320

Here loss percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100-loss\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100-5)}{100}\\\\S.P. =\frac{320\times 95}{100} =\frac{30400}{100} =Rs\ 304$

The Sell Price of the shoe at 5% loss is Rs 304.

Case 2.

C.P. = Rs 320

Profit = 20%

Here profit percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100+profit\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100+20)}{100}\\\\S.P.=\frac{320\times 120}{100}=\frac{38400}{100}=Rs\ 384$

The Sell Price of the shoe at 20% profit is Rs 384.

Case 3.

C.P. = Rs 320

S.P. = Rs 360

Now we need to find the gain percent.

First we will find the gain.

Gain is the difference of S.P with C.P.

Gain = $360-320 = 40$

Now Gain Percent can be calculated by dividing gain with the cost price and then multiplying it with 100

Gain Percent = $\frac{40}{320}\times 100 = 12.5\%$

Hence The Total Gain Percent is 12.5% when shoes are sold at Rs.360.

How many radians are in one degree, accurate to three decimal places?

qaws [65]

Now, if you recall, there are 180° in π radians, now, so how many radians in 1°?

$\bf \begin{array}{ccll}
de grees&radians\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
180&\pi \\
1&r
\end{array}\implies \cfrac{180}{1}=\cfrac{\pi }{r}\implies r=\cfrac{1\cdot \pi }{180}$

Y=x+12 4x+2y=27 Solve each system of equation algebraically

Maslowich

Solve by Substitution :

// Solve equation [1] for the variable y

[1] y = x + 12

// Plug this in for variable y in equation [2]

[2] 2•(x +12) + 4x = 27 [2] 6x = 3

// Solve equation [2] for the variable x

[2] 6x = 3 [2] x = 1/2

// By now we know this much :

y = x+12 x = 1/2

// Use the x value to solve for y

y = (1/2)+12 = 25/2 Solution : {y,x} = {25/2,1/2} y=x+12;4x+2y=27 Solution : {y,x} = {25/2,1/2} System of Linear Equations entered : [1] y=x+12 [2] 4x+2y=27 Equations Simplified or Rearranged : [1] y - x = 12 [2] 2y + 4x = 27
