Would it not be #"3-methylcyclohexanone....?"#

Explanation:

In organic nomenclature, we number SUCH that the positional numbers are minimized. CLEARLY, the carbonyl group represents #stackrel(1)C#...in the proffered name, the numbering has occurred anti-clockwise, rather than clockwise (as we face the page), so that the methyl group is numbered #stackrel(5)C#. Were we to number clockwise, as we face the page, we get the required #stackrel(3)C#.
