Question

the price of pen after a discount of 10% is rs. 45 . what is the original price?.

Answer 1

Answer:

Step-by-step explanation:

• Let the original price be Rs. x

A/Q, x of 90% = 45

⇒ 90 x = 4500

∴ x = 50.

Answer 2

Answer:

Let the original CP be 'x'

According to the question we get,

⇒ x - 10 % of x = Discounted Price

⇒ x - 10% of x = Rs. 45

⇒ x - 0.1x = Rs. 45

⇒ 0.9x = Rs. 45

⇒ x = Rs. 45 / 0.9

⇒ x = Rs. 50

Hence the original price is Rs. 50.
