#### Suppose I buy a dress at 10% discount. The price marked on it Rs 1000. How much did I pay him?

#### Here, Rs 1000 is the marked price

Marked Price = Rs 1000

Discount = 10%

Let’s find the discount

Discount = 10% × Marked Price

= 10% × 1000

= 10/100 × 1000

= 1/10 × 1000

= 100

So, Discount = Rs 100

Now,

Amount Paid to him = Marked Price − Discount

= 1000 − 100

= 900

So, I paid Rs 900 to him

Let’s say, Marked price is Rs 1000 and I paid Rs 900. What is the discount percentage?

Here,

Marked price = Rs 1000

Amount paid = Rs 900

Discount = Marked price − Amount paid

= Rs 1000 − 900

= Rs 100

Discount percentage = Discount/(Marked price) × 100%

= 100/1000 × 100%

= 1/10 × 100%

= 10%

So, discount is

10%

After a discount of 10%, a dress is bought in Rs 900. What is its marked price?

Discount percentage = 10%

Amount paid = Rs 900

Marked price = ?

Discount = Marked Price – Amount Paid

Discount = Marked Price – 900

Now, we know that

Discount percentage = Discount/(Marked Price ) × 100

10 = (Marked Price - 900)/(Marked Price) × 100

10 × Marked Price = (Marked Price – 900) × 100

10 × Marked Price = 100 × Marked Price – 900 × 100

900 × 100 = 100 × Marked Price – 10 × Marked Price

900 × 100 = 90 × Marked Price

(900 × 100)/90 = Marked Price

10 × 100 = Marked price

1000 = Marked Price

Marked Price = 1000

So, Marked Price = Rs 1000
