Answer 1

Solution :

$\underline{\bf{Given\::}}}}$

• Cost Price of a second - hand laptop = Rs.24000
• She spend repair on laptop = Rs.6000
• She sells the laptop (selling price) = Rs.45000

$\underline{\bf{Explanation\::}}}}$

$\bigstar$ According to the question Lisa has total Cost price,Adding both Cost price on laptop;

$\mapsto\sf{Total\:cost\:price=Rs.24000+Rs.6000}\\\\\mapsto\sf{Total\:cost\:price=Rs.30000}$

Now;

S.P. > C.P

⇒ Profit = Selling price - Cost price

⇒ Profit = Rs.45000 - Rs.30000

⇒ Profit = Rs.15000

$\longrightarrow\sf{Profit\:\%=\bigg(\dfrac{Profit\times 100}{cost\:price} \bigg)\%}\\\\\\\longrightarrow\sf{Profit\:\%=\bigg(\dfrac{15000\times 100}{30000} \bigg)\%}\\\\\\\longrightarrow\sf{Profit\:\%=\bigg(\cancel{\dfrac{1500000}{30000} }\bigg)\%}\\\\\\\longrightarrow\bf{Profit\:\%=50\%}$

Thus;

Lisa's profit % will be 50% .
