20% discount is given on the marked price. Therefore, if marked price is ₹ 100, then selling price is ₹ 80.

Let the marked price be ₹ x when the selling price is ₹ 900.

[tex] \: \frac{900}{x} \\ [/tex] [tex] = \: \frac{80}{100} \\ [/tex]

=> x [tex] = \: \frac{100}{80} \\ [/tex] × 900 = ₹1,125

Thus, The marked price is ₹1,125

SELLING PRICE=₹990

DISCOUNT=20%

MARKED PRICE = X

[tex] \frac{990}{x } = \frac{80}{100} [/tex]

[tex]x = \frac{80}{100} \times 990[/tex]

[tex]x = \frac{8}{1} \times 99[/tex]

[tex]x = 8 \times 99[/tex]

[tex]hence \: \: x = 792[/tex]

THUS,MARKED PRICE IS ₹792
