Answer:

54

Step-by-step explanation:

We'll call the number "ab".

From left to right, the value of this number will be [tex]10a+b[/tex].

From right to left, the value of this number will ve [tex]10b+a[/tex].

From the question,

[tex]10a+b=1.2(a+10b)\\10a+b=1.2a+12b\\8.8a=11b[/tex]

For a and b to be whole numbers,

[tex]\left \{ {{a=5} \atop {b=4}} \right.[/tex]

So the number is 54.
