well actually no, I want to leave the finance industry now. My plan was to just learn as much as I could before getting an MBA and then switching industries into something like marketing. What do you think of that?

is there a quicker way to solve these ds problems?
1. A, B>0, is a^b greater than 10,000?
1. a+b =20
2. b^a>10,000
OA is E
if you put in values it could be the easier but at the same time eyeballing values is risky...is there another way?
2. Is x^y>1?
1. x>1
2. y<1
OA is E
