Answer 1

let the digits be x and x+5 in ten's and unit's place so it can also be expressed as 10(x)+x+5=11x+5 .
When reversed, it can be expressed as 10(x+5)+x=>
11x+50. It is said that the number + reversed number =99=> 11x+5+11x+50=99=>22x+55=99=>
22x=99-55=44=> x=44/22=2. So the number can be
11x+5 or 11x+50=>11(2)+5 or 11(2)+50=>27 or 72.
