Which salt on treatment with soda lime gives ethane?

An aromatic kentone (X) has the molecular formula C_(10)H_(12)O_(2) . On vigorous oxidation, it yields a dibasic acid (Y) having the formula C_(9)H_(8)O_(5) which rapidly forms an anhydride on heating. (X) on strong heating with sodium hypobromite gives monobasic acid (Z) with the formula C_(9)H_(10)O_(3) . (Z), when heated with soda lime, gives 3-methylanisole. Interpret the above reactions and deduce the structures of (X), (Y), and (Z).
