Question

the Marked price of computer is 22000 after knowing 10% discount still makes a profit of 20% find the cost price of computer​

Answer 1

Given:

The market price of the computer: Rs.22000

After 10% discount, its cost be:

$\implies$ [22000 - (22000 × 10%)]

$\implies$ [22000 - (22000 × 10/100)]

$\implies$ (22000 - 2200)

$\implies$ 19800

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

The dealer made a profit of 20%

Then:

It's selling price was:

$\implies$ [x + (x × 20%)]

$\implies$ [x + (x × 20/100)]

$\implies$ (x + x/5)

$\implies$ (6x/5)

By the given condition:

6x/5 = 19800

$\implies$ x = 19800 × 5/6

$\implies$ x = 16500

Therefore:

Cost price of the computer is Rs. 16500
