# A man sold an article for Rs 495 and gained 10% on it. Find the cost price.

Cost Price is the amount at which the article was purchased. It is represented as CP.

## Answer: The cost price of the article is Rs 450.

Let's find the cost price of the article.

**Explanation:**

Given:

SP = Rs 495

Gain = 10%

CP = SP - Gain

=> CP = SP - Gain% of CP

Let CP = x

Substituting the values in the above equation, we get

x = 495 - 10% of x

x = 495 - 0.1x

x + 0.1x = 495

1.1x = 495

x = 495 / 1.1

x = 450

### Thus, for an article sold at Rs 495 at a gain of 10%, the cost price is Rs 450.
