A new cell phone plan is offering pricing based on average monthly use. Brandon and Jodie are comparing their average use to determine the best plan for them. Brandon's average monthly usage in 2001 was q minutes. Was this less than, greater than, or equal to Jodie's 2001 average monthly usage, in minutes?
(1) From January to August 2001, Jodie's average monthly usage was 1.5q minutes.

(2) From April to December 2001, Jodie's average monthly usage was 1.5q minutes.

1) INSUF. The Average is 1.5 q for 8 months, that is a total of 12 q for the 8 months. Nevertheless, we do not know anytthing aaboy the balance months. So INS.

2) The same. INS.

But taken together, we have all the information to solve the problem.

I would also say the correct answer should be C. However, the official MGMAT answer is B (I got this questions from the weekly question bank). Any idea why this is?

Ben's monthly average = q Therefore, the sum equals 12q

Now, if we can proof that Jodie's usage per year was higher than Ben's, we answered the question.

(1) Insufficient since only eight month (1.5q * 8 = 12q - for the whole year it could be higher than 12) (2) Sufficient since we are looking at a 9 month period (1.5q * 9 > 12q)
