GMAT3月新题（三）
<p> 67. 还有一个表，关于航空公司计算竞争系数的，阅读了半天才知道在说什么，主要是阅读上比较绕，这个就是没有<span word="jj">jj</span>的坏处了</p><p> 表里有用的数据就是<span word="X">X</span>城市到洛杉矶的航班数，大概数据是：<span word="A">A</span>，<span word="B">B</span>，<span word="C">C</span>,<span word="D">D</span>代表不同的航空公司，数字代表航线数量，问航空公司<span word="A">A</span>的竞争系数</p><p> <span word="A">A</span> <span word="B">B</span> <span word="C">C</span> <span word="D">D</span></p><p> <span word="LA">LA</span> 4,2,2,1.</p><p> 给了一个公式<span word="X">X</span>=<span word="a">a</span>/<span word="f">f</span>+<span word="n">n</span>/4</p><p> 解法是看清每个字母的定义，<span word="f">f</span>是本公司的航线数，<span word="n">n</span>是有多少个竞争对手, <span word="a">a</span>是竞争对手的航线总数</p><p> 结果应该是2.。。</p><p> 航空公司的竞争系数是2</p><p> 73. 有一题很绕 <span word="a">a</span> <span word="group">group</span> <span word="of">of</span> 3 <span word="of">of</span> <span word="battery">battery</span> <span word="containers">containers</span> <span word="each">each</span> <span word="contain">contain</span> 6 <span word="batteries">batteries</span>, 要<span word="go">go</span> <span word="through">through</span> <span word="a">a</span> <span word="inspection">inspection</span> <span word="of">of</span> 200 <span word="such">such</span> <span word="containers">containers</span>, <span word="with">with</span> 3 <span word="containers">containers</span> <span word="each">each</span> <span word="have">have</span> <span word="one">one</span> <span word="bad">bad</span> <span word="battery">battery</span>,<span word="while">while</span> <span word="others">others</span> <span word="contain">contain</span> <span word="no">no</span> <span word="bad">bad</span> <span word="battery">battery</span>, 问 <span word="fraction">fraction</span> <span word="of">of</span> <span word="bad">bad</span> <span word="batteries">batteries</span> <span word="over">over</span> <span word="inspected">inspected</span> <span word="batteries">batteries</span>.</p><p> 我选的1/400 应该是对的 这题我读了5边</p><p> 74. 有一题说<span word="N">N</span>是一个三位数，问这个三位数可否被3整除</p><p> <span word="A">A</span> 三个位数相加为9</p><p> <span word="B">B</span> 百位十位相同，且比个位大3 这题选<span word="D">D</span></p><p> 条件1不解释了</p><p> 条件2的话，因为百位和十位相同，而且比个位大三，所以我们不妨假设个位是<span word="x">x</span>，所以百位和十位就是<span word="x">x</span>+3，所以三个加起来就是3<span word="X">X</span>+6那一定就是3的倍数了</p>
