<h2> Question # 1</h2>

Answer:

The actual cost will be = 17,000 Rs

Step-by-step explanation:

Let us suppose 'C' is the actual cost of the table.

The money spent by shopkeeper on polishing and transportation = 1000 Rs

Total cost = $C + 1000$

As the profit $=12\frac{1}{2}\%\:=\:12.5\%\:$

So

Sale price without tax will be = $\left(C+1000\right)\:\cdot \frac{\left(100+25\right)}{100}$

$=\frac{\left(100+25\right)\left(C+1000\right)}{100}$

$=\frac{125\left(C+1000\right)}{100}$

$=\frac{5\left(C+1000\right)}{4}$

Sales Tax = $\frac{5\left(C+1000\right)}{4}\times \frac{6}{100}$

so

The total price paid by Arvind is :

$5\:\frac{\left(C+1000\right)}{4}\:\cdot \:\frac{106}{100}\:=\:23,\:850$

$\frac{53C}{40}+1325=23850$

$53C+53000=954000$

$53C=901000$

$\frac{53C}{53}=\frac{901000}{53}$

$C = 17, 000$ Rs

Therefore, the actual cost will be = 17,000 Rs

<h2 /><h2> Question # 2</h2>

Answer:

The overhead charges were = 3171000 Rs

Step-by-step explanation:

Gagan bought a plot of land for the price = 2,35,000

Profit = 40% of 2,35,000

= $\frac{40}{100}\times 235000$

$=94000$ Rs

Sale Price after 40% profit = 235000 + 94000

= 329000 Rs

Overhead Charges = Final Sale Price - Sale Price after 40% profit

= 3500000 - 329000

= 3171000

Therefore, the overhead charges were = 3171000 Rs

<h2 /><h2> Question # 3</h2>

Answer:

The required Cost Price = 2800 Rs

Step-by-step explanation:

Marginal Price = 4200 Rs

Sales Price $=4200\times 80/100$

$=3360$

According to the information given in the question

$Cost\:Price+Cost\:Price\:\times \:20/100=3360$

$Cost\:Price\left(1+1/5\right)=3360$

$Cost\:Price\times \frac{6}{5}=3360$

$Cost\:Price=3360\:\times \:\frac{5}{6}$

$Cost\:Price=2800$

Therefore, the required Cost Price = 2800 Rs

Solar panels installed in a backyard have a cross section that is a right triangle. The diagram shows the approximate dimensions

Citrus2011 [14]

Answer:

About 4.2 ft

Explanation:

The area of the traingle can be calculated in two ways.

$A=\frac{1}{2}\text{width}\cdot\text{length}$

where width = 4.4 ft and length = 13.6 ft.

Putting in the values for width and length gives

$\begin{gathered} A=\frac{1}{2}13.6\cdot4.4_{} \\ \boxed{A=29.92ft^2} \end{gathered}$

The other way that the area can be calculated is

$A=\frac{1}{2}\cdot\text{height}\cdot\text{base}$

where height = vertical length and base = 14.3 ft; therefore.

$\begin{gathered} A=\frac{1}{2}14.3h \\ A=7.15h \end{gathered}$

This must equal the area of the triangle we found above; therefore,

$A=29.92=7.15h$ $29.92=7.15h$

dividing both sides by 7.15 gives

$h=\frac{29.92}{7.15}$ $\boxed{h\approx4.2ft}$

which is our answer!
