A two digit number reversed and multiplied by 4 is 3 more than the original digit. what is the digit?

• If no is xy , then
  
  10x+y = 4*(10y+x)-3= 40y +4x-3
  6x-39y +3 =0
  2x-13y +1 =0
  13 y =2x+1
  when y=1, x=6
  
  so number is 61.

• Two digit = 61.
  
  After reversing, it will be 16
  
  Multiplied that by 4 = 16*4 = 64
  No we get, 3 more than original digit. (i.e, 64-3 =61)
