27
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...
hey madan thts right ...
10X+y =3(X+Y)
from where 10 cums
it's 27
the num is 27 for sure......
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
-.-
X is a single digit..
10X + Y = XY
it can also be just zero
