The sum of the digits of a two digit number is 14.If the number formed by reversing the digits is less than the original number by 18.Find the original numbers .

Posted by Yash Thadani (Apr 23, 2017 12:34 a.m.) (Question ID: 5001)

  • Answers:
  • Let x = the 10's digit
    Let y = the units
    :
    10x + y = the original two digit number
    :
    The sum of the digits of a two-digit number is 14.
    x + y = 14
    :
    "If the digits are reversed, the number is 18 less than the original number."
    Rev no. = orig no. - 18
    10y + x = 10x + y - 18
    10y - y = 10x - x - 18
    9y = 9x - 18
    simplify, divide by 9
    y = x - 2
    :
    In the sum equation replace y with (x-2)
    x + (x-2) = 14
    2x = 14 + 2
    2x = 16
    x = 8
    obviously y = 6
    :
    86 is the original number
    :
    :
    Check solution in the statement:
    "If the digits are reversed, the number is 18 less than the original number."
    68 = 86 - 18
