Since x, y, and z are consecutive odd integers, try x = 3, y = 5, and z = 7. So, (3+7)\/(5) = 2, which is an integer. To confirm, try a different set of numbers: x = 7, y = 9, and z = 11. So, (7+11)\/(9) = 2, again an integer. Thus, statement II must be true, and your correct answer must contain statement II. So,<strong> eliminate choices (A) and (C).<\/strong><\/p>\n<p>Now consider statement I. If x = 3 and y = 5, x + y = 8. In fact, odd + odd is always even, so statement I must also be true. The correct answer must also contain statement I, so you can also <strong>eliminate choice (B).<\/strong><\/p>\n<p>Are you keeping track of the answer choices you are eliminating on your noteboard? That's especially important on these Roman Numeral questions!<\/p>\n<p>Finally, in statement III, xz is the product of two odd numbers, which is always odd. Thus, statement III cannot be true, so <strong>(D) is the correct choice.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p>The post <a rel=\"nofollow\" href=\"https:\/\/gmat.kaptest.com\/2014\/03\/10\/gmat-problem-solving-tips-roman-numeral-questions\/\">GMAT Problem Solving: Tips for Roman Numeral Questions<\/a> appeared first on <a rel=\"nofollow\" href=\"https:\/\/gmat.kaptest.com\">Kaplan GMAT Blog<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s finally time!
