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