loss= 30%
sold amount= rs 63000
the original price of the laptop.
[tex]cp = \frac{100 \times selling \: price}{100 - loss\%} [/tex]
[tex]cp = \frac{100 \times 63000}{100 - 30\%} [/tex]
[tex]cp = \frac{100 \times 63000}{70} [/tex]
[tex]cp = 100 \times 900[/tex]
[tex]cp = 90000[/tex]
therefore, the original price of the laptop is rs 9000.
