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.
