Find a two digit number which is doubled and after that add +2 in it. and then reverse the number we would get the actual number.
(Example : xy * 2 = pq => pq+2 = xy )

• Ans= 25
  
  Let the two digit number be 10x+y
  Adding 2 after doubling the number is reverse of the number.
  So 2(10x+y)+2 = 10y+x
  19x -8y +2=0
  Above equation satisfies for the value, x=2, y=5
  So the number is 10*2+5= 25

• 25*2=50+2=52 & reverse the 52 is 25

• Ans is 25
  ((10*a+b)*2)+2=10b+a
  19a-8b+2=0
  So by simply putng
  A=2
  B=5

• 25*2=50+2=52
  52 reverse 25

• 25
  25*2=50
  50+2=52
  reverse 25

• suppose number is 10 then 10*2=20
  20+2=22
  nd reverse num is also 22
  ans is 10
