Question :

The selling price of a TV is 21,500 and that of a DVD player is 1800. The cost prices are 13,500 and 1250 respectively. If eight pairs of TV and DVD players are sold, calculate the total cost price and profit.

Answer :

$\sf\pink{Given:}$

• Selling price of TV is 21500

• Selling price of DVD player is 1800

• Cost price of TV is 13500

• Cost price of DVD is 1250

$\sf\pink{To\:Find:}$

• Cost price of eight pairs of TV and DVD player ?

• Profit ?

$\bf\red{Total\:cost\:price\:of\:eight\:TV = 8\times 13500}$

$\bf\red{Total\:cost\:price\:of\:eight\:TV = 108000}$

$\bf\purple{Total\:cost\:price\:of\:eight\:DVD = 8\times 1250}$

$\bf\purple{Total\:cost\:price\:of\:eight\:DVD = 10000}$

Profit after 1 TV = selling price - cost price

$\longrightarrow\bf{21500 - 13500}$

$\longrightarrow\bf{8000}$

Profit after 8 TV = 8 × 8000

$\longrightarrow\bf{64,000}$

Profit after 1 DVD = selling price - cost price

$\longrightarrow\bf{1800 - 1250}$

$\longrightarrow\bf{550}$

Profit after 8 DVD = 8 × 550

$\longrightarrow\bf{4400}$
