Answer:
26
Step-by-step explanation:
Let the digits be x and y;
3x = y; [condition given]
The original number = 10x + y;
= 10x + 3x (from the given condition)
= 13x
The reversed number = 10y + x
= 10(3x) + x
= 30x + x
= 31x
According to the question:
original number + 36 = reversed number
13x + 36 = 31x
18x = 36
x = 36/18
x = 2
Therefore, original number = 13x = 13(2)= 26
