Answer 1

☯ Given :

$\begin{lgathered}\bullet\:\:\textsf{Selling price = SP = \textbf{810 Rs.}}\\\bullet\:\:\textsf{Profit = \textbf{60 Rs.}}\end{lgathered}$

$\rule{130}{1}$

☯ Solution :

$:\implies\sf Cost\:Price = Selling\: Price - Profit \\\\\\:\implies\sf Cost\:Price = 810 - 60 \\\\\\:\implies\underline{\boxed{\sf Cost\:Price = 750\:Rs}}$

$\therefore\:\underline{\textsf{Cost price of the fan is \textbf{750 Rs}}}.$

$\rule{170}{2}$

$\dashrightarrow\sf\:\: Profit\: Percentage = \dfrac{Profit}{Cost\:Price}\times 100\\\\\\\dashrightarrow\sf\:\: Profit\: Percentage = \dfrac{60}{750}\times100\\\\\\\dashrightarrow\:\:\underline{\boxed{\sf Profit\: Percentage = 8 \:\%}}$

⠀

$\therefore\:\underline{\textsf{The Profit Percentage is \textbf{8 \%}}}.$

$\rule{170}{2}$

$\boxed{\begin{minipage}{7 cm}\boxed{\underline{\underline{\bigstar\:\bf\:Extra\:Shots\:\bigstar}}}\\\\ \tt 1) Profit = SP - CP\\\\2) Loss = CP - SP\\\\3) Profit\% = (Profit in Rs.)*100/CP\\\\4) Loss\% = (Loss in Rs.)*100/CP\\\\5) SP = CP*(100+P\%)/100\\\\6) SP = CP*(100-L\%)/100\\\\7) CP = SP*100/(100+P\%)\\\\8) CP = SP*100/(100-L\%)\\\\9) Discount =MP - SP\\\\10) Discount\%=(Discount in Rs.)*100/MP\\\\11) SP = MP*(100-D\%)/100\\\\12) MP = SP*100/(100-D\%)\\\\\end{minipage}}$

Answer 2

Given:-

★ SP of a fan = Rs.810

★Profit made by the dealer = Rs.60

To Find:- The C.P. of the fan and the profit percent.

solⁿ -

We know that,

$\boxed{cost \: price = sp \: - \: profit}$

So,

$\boxed{cost \: price = 810 \: - \: 60 = rs.750}$

$\therefore \: cost \: price \: of \: thefan \: is \: rs.750$

Now, for profit percent,

$\implies\frac{profit}{cost \: price} \times 100$

$\implies \frac{60}{750} \times 100$

$\implies8\%$

$\therefore \: profit \: \% \: is \: 8\%$

$\rule{170}2$

$\boxed{\begin{minipage}{6.5 cm}\bigstar\underline{\bf{Extra brainly knowledge :}}\\ \\ \sf SP=CP\times(100+\sf Profit)\%\\ \\SP=CP\times(100-Loss)\%\\ \\Profit\%=\dfrac{Profit}{CP}\times100 \\ \\Loss\%=\dfrac{Loss}{CP}\times100\end{minipage}}$
