Hi boomgoesthegmat,

You've been posting large blocks of questions, but you haven't discussed any of YOUR attempt at solving them. Why did you get them wrong? What did you miss? What aspect of each question are you really interested in. It's a good bed that all of these questions have been discussed somewhere online already, so what specifically are you looking for when YOU post them?

I'm trying to learn every way possible to solve questions so I have tons of ammo when I take the test.

OA: C
Average of Car X = 25.0 miles/gallon
Average of Car Y = 11.9 miles/gallon

Total distance driven by each = 12,000 miles.

Fuel used by Car X = 12,000/25 = 480 gallons
Fuel used by Car Y = 12000/11.9 = 1000 gallons approx.

Difference between the fuel consumed = 1000 - 480 = 520 gallons.

Correct Option: C
