. The sum of the digits of a two digit number is 8. When 18 is added to the number, the digits are reversed. Find the number?

• ans:35
  let the no. be 10x+y
  sum of the digits ie. x+y=8 ---> eqn1
  when 18 is added,digits reversed ie (10x+y)+18=10y+x ----> eqn2
  solving 2 eqns.,
  x=3 , y=5
  hence the no. is 3*10+5=35

• take 3+5=8
  35+18=53
  35 is reversed as 53
  so ans is 3&5

• let the number is xy
  so x+y=8
  xy+18=yx
  if u like to save the time possible number are(17,26,35,44)
  u find 35 is correct ans

• 17,26,35,44,53,62 ,71 and 80 are the only 2 digit numbers whose sum is 8. Check for number whose digits get reversed when added with 18. So 35 is the answer

• 35
  3 and 5 is8
  after adding 18 to 35, it becomes 53
  so the answer is 35
