The table above shows imports for three types of steel over a six month period. Use this information to answer the following questions.
What was the approximate ratio of sheet steel and coil steel imports in the first 3 months of the year?
Explanation: Looking at the working for the previous question you can see that the totals are: Coil 93 thousand tons Sheet 113 thousand tons Therefore the ratio is 113:93 or approximately 11:9 One of the key lessons to learn from answering questions of this type is to write down your intermediate results and working-out. You will often find that you can save time in subsequent questions if you do this.
