Answered by sohum2002pokemon

Let the 2 digit number be 10x+y
The number formed by interchanging the digits is 10y+X
Therefore,
(10x+y)+(10y+X)=99
11x+11y=99
X+y=9----(1)
There should be another equation for solving the question. The sum of digits should be given
Please check...
Anyways. The answer is 45 and 54
