MBA Center - 08-31-2010
The Graduate Management Admission Test (GMAT) is a computer adaptive standardized test for measuring aptitude to succeed academically in graduate business studies. Business schools commonly use the test as one of many selection criteria for admission into an MBA program. MBA Channel presents sample questions every week.
Answer: (B): 135
Explanation:
This looks intimidating due to the calculations that appear to be involved until you recognize that 19.5 is actually 13(1.5) and 7.5 is 5(1.5), so the triangle created by two sides and a diagonal has got to be a 5-12-13 triangle. The long side must therefore be 12(1.5), or 18. Knowing the base and the height, we calculate:
7.5(18) = 7.5(9)(2) = 15(9) = 3(5)(9) = 3(45) = 135
Choice (B) is correct.
