i am a 5 digit palindromic number. My third digit is 5 more than my fifth digit , my fourth digit is 2 times greater than my first digit. The sum of my digit is 14 What number am i?

  • math -

    the number is abcba

    c = a+5
    b = 2a
    2a+2b+c = 14

    (a,b,c) = (1,3,6)
    the number is 13631

    Note the possibly confusing "2 times greater" which means "3 times as much".

    Instead of using algebra, if we just start guessing, then

    if we let a=1, that makes c=6 and 2a+c=8, so dividing that up equally into 2b, b=3.
