Hi All,

We're told that a two-bedroom apartment costs 50% more to rent than a one-bedroom apartment. If Alex were to rent a two-bedroom apartment for X months it would cost him the same amount as it would to rent a one-bedroom for 12 months. We're asked for the value of X. This question can be solved in a couple of different ways. TESTing VALUES works really well (as ArjunJag1328 has shown); it can also be solved by TESTing THE ANSWERS.

Since a two-bedroom apartment costs 50% more than a one-bedroom apartment, we need to find a value for X that, when increased by 50%, equals 12. Since a 50% increase is NOT the same as DOUBLING a value, we can eliminate Answer A. Let's TEST Answer B first.

Answer B: 8 months

IF... X = 8, then 50% MORE than 8 would be (1.5)(8) = 12

This is an exact match for what we were told, so this must be the answer.

Final Answer:

GMAT assassins aren't born, they're made,
