B Correct answer
Explanation

Let the price of each article = Rs. x and number of articles = y,

So, CP of articles = Rs. 360,

That means, x*y = 360 ----------------(1),

On reducing the price by 10%,

(90x/100)*(y + 10) = 360 -----------------(2),

From (1) and (2),

10xy = 9xy + 90x,

xy = 90x,

y = 90,

So, original number of articles is 90. 

Therefore, the original price of each article = 360/90 = Rs. 4.
