Answer 1

Answer:

Step-by-step explanation:

M.P=280

Discount=25%

So selling price= 280-25%0f 280

=280-(25÷100×280)

=280-(70)

=210 rs =S.P

Discount allowed =Marked price-selling price

=280-210

=70 rs

Answer 2

Answer:

$\underline{\bigstar\:\:\textsf{Selling Price of Book :}}$

$:\implies\tt SP=MP\times (100-Discount)\%\\\\\\:\implies\tt SP =280 \times (100 - 25)\%\\\\\\:\implies\tt SP = 280 \times75\%\\\\\\:\implies\tt SP =280 \times \dfrac{75}{100}\\\\\\:\implies\tt SP = 280 \times \dfrac{3}{4}\\\\\\:\implies\tt SP = 70 \times 3\\\\\\:\implies\underline{\boxed{\textsf{\textbf{SP = Rs. 210}}}}$

$\rule{160}{1}$

$\underline{\bigstar\:\:\textsf{Discount on Book :}}$

$\dashrightarrow\tt\:\: Discount=MP-SP\\\\\\\dashrightarrow\tt\:\: Discount=Rs.\:(280-210)\\\\\\\dashrightarrow\:\:\underline{\boxed{\textsf{\textbf {Discount = Rs. 70}}}}$

$\rule{200}{2}$

$\boxed{\begin{minipage}{6.5 cm}\underline{\text{Some Important Formulae Related to it :}}\\ \\ SP=CP\times(100+\sf Profit)\%\\ \\SP=CP\times(100-Loss)\%\\ \\Profit\%=\dfrac{Profit}{CP}\times100 \\ \\Loss\%=\dfrac{Loss}{CP}\times100\end{minipage}}$
