Let,the marked price of the almirah = Rs. x
Assume, x as a variable to do the further mathematical calculations.
So, the discount amount = x × 5/100 = Rs. x/20
The selling price = x – x/20 = Rs. 19x/20
Now,if we compare the value of selling price that is given in the question and the value of the selling price that we have calculated,then we will get the following mathematical equation,
19x/20 = 5225
x = 5225 × 20/19 = 5500
Hence, the marked price of almirah is 5500.
