Answer: 3.70
Explanation: Stock turnover can be calculated using following formula :-
[tex]stock\:turnover\:ratio=\frac{cost\:of\:goods\:sold}{average\:stock}[/tex]
where,
cost of goods sold =598,600
average stock = 162,000
now, putting the values into equation above, we get :-
[tex]stock\:turnover\:ratio=\frac{598,600}{162,000}[/tex]
= 3.70
