Answer 2

EXPLANATION:-

Let the unit digit=x

then tens digit=11-x

And the digit will be :-

10(11-x)+x

110-11x

So after interchanging,

Unit digit=11-x

Then tens digit=x

and the digit will be :-

11x+11

Now It if given that If we interchange the digits the new number is 45 more than the original number,

So equation can be-

Previous digit+45=new digit

Previous digit=110-11x

New digit=11x+11

A.T.Q

110-11x+45=11x+11

ANSWER-

x=6.54...
