A. 6 B. 8 C. 9 D. 10 E. 18 A fast and easy approach is to assign a "nice" value to the monthly rent of a ONE-bedroom apartment. Let's say the rent on a ONE-bedroom apartment is$100 per month

A two-bedroom apartment costs 50% more to rent than a one-bedroom apartment
50% of $100 =$50
So, the rent on a TWO-bedroom unit = $100 +$50 = $150 per month 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 At$150 per month for x months, the TOTAL rent for a TWO-bedroom apartment = 150x
At $100 per month for 12 months, the TOTAL rent for a ONE-bedroom apartment = 1200 dollars So, we can write: 150x = 1200 So, x = 1200/15 = 8 Answer: B Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use my video course along with Sign up for free Question of the Day emails And check out all of these free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert Elite Legendary Member Joined 23 Jun 2013 Posted: 10197 messages Followed by: 496 members Upvotes: 2867 GMAT Score: 800 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 Brent 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.

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. What is x? A. 6 B. 8 C. 9 D. 10 E. 18 The OA is B. Let the one-bedroom rent =$2 per month, implying that the two-bedroom rent = 2 + (50% of 2) = 2 + 1 = $3 per month. Since the rent for a one-bedroom apartment =$2 per month, the total amount to rent a one-bedroom apartment for 12 months = 2*12 = $24. For$24, the number of months yielded for a $3-per-month two-bedroom apartment = 24/3 = 8. The correct answer is B. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

We can let n = the cost to rent a one-bedroom apartment per month. Therefore, the cost for a two-bedroom apartment per month = 1.5n; thus: 1.5nx = 12n 1.5x = 12 x = 8 Answer: B _________________ Scott Woodbury-Stewart Founder and CEO scott@targettestprep.com See why Target Test Prep is rated 5 out of 5 stars on BEAT the GMAT.
