We are given that the discount is 5%. This means that for Rs.100, the discount is Rs.5.
Therefore, selling price =Rs.100−Rs.5=Rs.95.
Thus on a selling price of Rs.95, the marked price is Rs.100.
On a selling price of Rs.5,225, the marked price =10095×5225=5500.
Therefore, marked price of the tape recorder is Rs.5,500.
