A. $1400
B. $1300
C. $1200
D. $1100

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

Let's denote the actual price of the article as "P."

According to the given information, after decreasing 24%, the discounted price becomes $912. We can represent this as an equation:

P - 0.24P = $912

Now, let's solve for P:

0.76P = $912

Divide both sides by 0.76 to find the actual price:

P = $912 / 0.76 P = $1200

So, the actual price of the article is $1200.
