Accounting Ratios EDIT: Close thread

[5v3d3b0]

Am working through some past papers and this question came up after looking at balance sheets for 2 companies:
For each company calculate 2 ratios for each of the following headings:
1. Profitability
2. Efficiency
3. Liquidity and Gearing

I would use (but am very unsure) :
1 - EDIT: Profit Margin and Gross Margin
2 - Asset turnover and Inventory Turnover
3 - Gearing and Current Ratio

Can someone give me some clarity? Please only respond if you know your stuff, thanks.

EDIT: Sat the exam already
