There is a number which is very peculiar. This
number is three times the sum of its digits. Can you
find the number?

  1. Let number be XY
    sum of the numbers =X+Y
    Given 10X+y =3(X+Y)
    7x = 2y
    x/y = 2/7
    So x=2,y=7

    Number is 27...

    Number is not so peculiar... the all multiples of 9 has such type of peculiarity.. like 45,36,18.... its sum are 9 and is multiple of 9... there are few peculiar numbers nike 4104,1729,91... etc
