Did the profit exceed$4 million on sales of 380,000 units?

Two important notes from the stem:
A. The profit from the sale increases with the number of units sold, so the profit on sales of 2 units is more than the profit on sales of 1 unit;
B. That increase is not proportional, so even though the profit on sales of 2 units is more than the profit on sales of 1 unit, it's not twice as much (it can be 1.1 times more, 5 times more, ..., 1,000,000 times more).

(1) The profit exceeded $2 million on sales of 200,000 units --> since the increase is not proportional we can not say whether the profit exceeded$4 million on sales of 380,000 units. Not sufficient.

(2) The profit exceeded $5 million on sales of 350,000 units --> since the profit on sales of 350,000 units, which is less than 380,000 units, is ALREADY greater than$4 million, then the profit on sales of 380,000 units will definitely be greater than $4 million. Sufficient. Answer: B. _________________ Intern Joined: 25 Jul 2012 Posts: 33 Location: India GMAT Date: 08-03-2013 WE: Engineering (Computer Software) Followers: 0 Kudos [?]: 5 [0], given: 56 Re: The profit from the sale of a certain appliance increases [#permalink] 20 Jan 2013, 18:41 Bunuel wrote: SOLUTION: The profit from the sale of a certain appliance increases, though not proportionally, with the number of units sold.

Sufficient. Answer: B. The data is given only for 350,000 units. Here we are taking assumption that next 30,000 units fetch no loss. Is this valid point ? I'm confused.

Sufficient. Answer: B. The data is given only for 350,000 units. Here we are taking assumption that next 30,000 units fetch no loss. Is this valid point ? I'm confused. Please read solutions carefully. We are told that: the profit from the sale increases with the number of units sold. (2) says that the profit exceeded$5 million on sales of 350,000 units. Now, the profit on sales of 350,000 units, which is less than 380,000 units, is ALREADY greater than $4 million, then the profit on sales of 380,000 units will definitely be greater than$4 million.
