Question

If selling price = ₹ 900. Discount is 20%, then find the marked price.

Answer 1

Here, selling price = ₹ 900, discount = 20%

Let the marked price be ₹ 100

Since, the discount given = 20%

∴ Amount of discount = ₹ 20

∴ Selling price = 100 – 20 = ₹ 80

Let actual marked price be ₹ x

∴ For marked price of Rs x, selling price is Rs 900

\[\therefore \frac{900}{x} = \frac{80}{100}\]

∴ 900 × 100 = 80 × x 

\[\Rightarrow x = \frac{100}{80} \times 900\]

= `90000/80`

= ₹ 1,125

Thus, the marked price is ₹ 1,125.
