Interesting and Simple questions. All options have answer A

Will try to answer so that we don't have to actually solve.

1. Which year saw the greatest percent change in sales from the previous year?

A. 2004 to 2005
B. 2006 to 2007
C. 2007 to 2008
 
It was clearly A because it shows the greatest change. Had the options had 2008 to 2009, then also we would have gone by the same logic. We would have considered that in 2008-09, the previous was more giving a high denominator.

Question 2 : We can see that 4 values are well above $70M, hence the avg has to be more than $70M

Question 3: The sales in ascending order are 55,60,60,85, 87,95,95, Counting the fourth gives us 85 for 2006

1. Which year saw the greatest percent change in sales from the previous year?
2004-2005 - 60-95 = approx 35 millions.
2006-2007 - 83-89 = approx 6 millions.
2007-2008 - 89-93 = approx 4 millions.

We can see the greatest difference is in A,  Hence A.

2.The average sales volume for the period 2004 to 2010 was:
We can add all the values mentioned: (60+95+83+89+93+54+60)/7 = approx 77. So yes >70 million $.
Also, alternatively, since most of the values are >70, the avg. will be greater than 70.
 Answer A.

Which year from the period 2004 to 2010 had the median sales figure?
Again, we have all the values, arranging them in ascending order we get: 54,60,60,83,89,93,95. Now the median is always the middle no. of the set = 83, which corresponds to the year 2006.
 Hence A.

For part-2 of the question, we don't need to calculate average. We can simply eyeball the chart and select >$70mm.

Here is how:
Three years (2004, 2009, 2010) have values very close to $60mm. Other three years (2006, 2007, 2008) have values greater than $80mm. These six will have average >$70mm. Additionally, one more year (2005) which is also the highest which take average more towards the higher side.
