Let no be 10x + y, so the no is written as XY.
for example: if it is 25, it is 10×2+5.
So,our equation formed as 10x + y + 27 = 10y+X
9x + 27 = 9y
X + 3 = y
now the upper limit for a digit of a no is 9
Y-------X
96,85,74,63,52,41
We can take X= o because if we did it wont be a 2-digit number
So, the number are :-
14, 25,36,47,58,69.
hope it helps
