Answer:
The merchandise inventory turnover during 2012 is 8 times. 
Explanation:
The following information is given:
Sales -  $ 2,000,000
Cost of goods sold - $1,400,000
Merchandise inventory Beginning of year -  $ 155,000
Merchandise inventory End of year - $ 195,000
After considering these information, it is easy to calculate the merchandise inventory turnover. The formula is shown below:
Merchandise Inventory Turnover =  COGS ÷ Average inventory
where average inventory = (opening inventory + ending inventory) ÷ 2
So, 
Average inventory = ( $ 155,000 + $ 195,000) ÷ 2
                                = $175,000
Now, we can compute easily 
Merchandise Inventory Turnover = 1,400,000 ÷ $175,000
                                                        = 8 times
Thus, the merchandise inventory turnover during 2012 is 8 times.
