Answer 2

let's begin

if,

the single local digit = x

the tenth local digit = y

so,the number is 10y + x

and y = 3x..........(i)

10y + x + 36 = 10x + y

or,10y + x - 10x - y = -36

or,9y - 9x = -36

or,9(y -x) = -36

or,y - x = -36/-9

or,y- x = 4........(ii)

if, y = 3x then

3x - x = 4

or,2x = 4

or,x = 4/2

or,x = 2

if,x = 2 then,

y = 3×2

y = 6
