在GMAT綜合推理的4大題型中，圖表題和表格題一般來說是難度較低的，但世事無絕對，這兩類題型中偶爾也會出現(xiàn)一些難度較高的題目。下面是小編為大家整理收集的關(guān)于GMAT綜合推理IR圖表和表格類難題實(shí)例分析思路的相關(guān)講解，希望對大家有所幫助。

　　GMAT綜合推理表格類難題

　　The table below estimates XTO Energy's Natural Gas reserves, production, and revenue for years 1 through 12.

　　Beginning reserves and annual production are measured in Billions of cubic feet (Bcf). Price is sold at dollar per Million cubic feet. Revenue is measured in millions of dollars ($ M).

　　For each of the following statements, select True if the statement can be verified to be true based on the information provided. Otherwise, select False.

　　1. In at least 1 year, the annual production exhausted the entire supply of reserves remaining for XTO Energy.

　　2. The rate of production annually is estimated to increase then decrease over years 1 through 12

　　3. Cumulative revenue expected over years 1 through 12 is no more than $80M

　　正確答案：

　　T、T、F

　　題目解析：

　　圖表信息展示的是 XTO公司1-12年，每年年初的庫存量，當(dāng)年的產(chǎn)量，平均價格和收入。

　　第一問問的是：XTO公司當(dāng)年的生產(chǎn)時，把公司供應(yīng)的原材料用完了，對應(yīng)到圖表上就是問的，當(dāng)年的產(chǎn)量是否大于當(dāng)年年初的庫存量，如果大于等于，那就表示用完了庫存量，如果小于，那就沒有用完。最后一年，兩個數(shù)字相等，所以存在，所以應(yīng)該選T。

　　第二問：rate of production和產(chǎn)量是呈正比的，產(chǎn)量是先增后減，所以答案是T

　　第三問：把最后一列1-12年的revenue的整數(shù)加起來是80，所以肯定大于80，答案是F

　　GMAT綜合推理圖表類難題

　　The graph models the hypothetical mass, in kilograms, of a Tyrannosaurus rex up to 30 years of age. Points A, B, and C represent the masses for a Tyrannosaurus rex at ages 12,16, and 20, respectively, according to the model.

　　From each drop-down menu, select the option that creates the most accurate statement based on the information provided.

　　For integer values of the age from 12 to 30, the average (arithmetic mean) mass falls approximately between __1__ kilograms.

　　The percent change in the mass from age 12 to age 16 is approximately __2__ the percent change in the mass from age 16 to age 20.

　　1.

　　A 2,000 and 3,000

　　B 3,000 and 4,000

　　C 4,000 and 5,000

　　2.

　　A equal to

　　B 2 times

　　C 3 times

　　正確答案：

　　C C

　　解題思路：

　　1. 12到20, 平均數(shù)約為3000，總計(jì)為3000*9=27000;21到30，平均數(shù)約為5500，總計(jì)為5500*10=55000。

　　因此總平均數(shù)約為27000+55000/19，約等于4300，超過4000，所以選C。

　　2. A到B的增長率為2000/1000=200%=2;B到C的增長率為2000/3000=2/3。

　　因此增長率比值為2/(2/3)=3倍，所以選C。
