Question

the Marked price of a computer is 22000 after allowing a 10 % discount dealer still makes a profit of 20%. find the cost price of the computer

Answer 1

$\textbf{Answer :}$

The market price of the computer is Rs 22000

After 10% discount, its cost be

= Rs [22000 - (22000 × 10%)]

= Rs [22000 - (22000 × 10/100)]

= Rs (22000 - 2200)

= Rs 19800

Let us take the cost price of the computer be Rs x

The dealer made a profit of 20%

Then, its selling price was

= Rs [x + (x × 20%)]

= Rs [x + (x × 20/100)]

= Rs (x + x/5)

= Rs (6x/5)

By the given condition,

6x/5 = 19800

→ x = 19800 × 5/6

→ x = 16500

∴ the cost price of the.computer is Rs 16500

Answer 2

let the cost price of computer= x

ATQ

after allowing 10% of discount on mark price he still makes profit of 20%

that means

$22000 \times \frac{(100 - 10)}{100} = x \times \frac{(100 + 20)}{100}$

$22000 \times \frac{90}{100} = x \times \frac{120}{100} \\ \\ 19800 = \frac{6x}{5} \\ \\ x = 19800 \times \frac{5}{6} \\ \\ x = 3300 \times 5 \\ \\ x = 16500$
