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.
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.
