Answer:

The Cost Price of the Laptop is Rs. 36000.

Step-by-step-explanation:

Given :

Marked price = Rs. 34000

Discount of = 10%

Loss occurred = 15%

To find :

The Cost price of the Laptop

Solution :

Find the discount Amount -

$\tt{\longrightarrow} \: Discount \: = 10\% \: of \: 34000$

$\tt{\longrightarrow} \: Discount \: = \dfrac{10}{1\cancel{00}} \times 340\cancel{00}$

$\tt{\longrightarrow} \: Discount \: = 10 \times 340$

$\tt{\longrightarrow} \: Discount \: = 3400$

Amount discounted = Rs. 3400

$\rule{300}{1.5}$

$\boxed{\textsf{Selling Price = Marked Price - Discount Price}}$

$\tt{\longrightarrow} \:SP = 34000 - 3400$

$\tt{\longrightarrow} \:SP = 30600$

Selling Price of the Laptop is Rs. 30600

$\rule{300}{1.5}$

Here ;

• Selling Price = Rs. 30600
• Cost Price = ??
• Loss % = 15%

★ ${\boxed{\sf\:{CP = \frac{100}{(100 - loss\%)} \times SP}}}$

$\tt{\longrightarrow} \: CP = \dfrac{100}{(100 - 15)} \times \: 30600$

$\tt{\longrightarrow} \: CP = \dfrac{100}{85} \times \: 30600$

$\tt{\longrightarrow} \: CP = 100 \times \: 360$

$\tt{\longrightarrow} \: CP = 36000$

Cost Price = 36000

$\therefore$ The Cost Price of the Laptop is Rs. 36000.
