Answer 1

hii mate!!

Let the original number be "x" 
and the reversed number be "y"

Given:
      sum of these 2  = 99
     ie.,  x + y = 99     ----------> (A)
       y = 9 + x (given 9 more than original)     --------> (B)

solving these 2 eqns: (A) & (B)
      we get x = 45 and reversing it we get y = 54

Ans: 45 is the original number and 54 is the reversed number
               

hope it helps !!☺☺☺☺☺☺☺
