Answer a few math questions before 9:30. Thanks for your speed The four-year turnover of two department stores in a city is shown in the table below 2005 2007 2009 2010 First department store 7000 9600 11000 14000 The second department store 5000 7800 9200 13000 (2) In which of the four years, the turnover of the 100th company and the second department store is the closest? What percentage of the turnover of the second department store in 2007 is higher than that in 2005? The highest mountain in the world, Mount Qomolangma, is 8844m higher than sea level, which is often expressed as + 8844m. Then the height of sea level is () which is different from that of Mount Qomolangma () The results of one minute sit up test for boys and girls in a class are recorded below 15 times 16-24 times 25-32 times more than 32 times Boys 3 7 13 2 Girls 1 4 16 4 Among the students whose scores of 1 minute sit ups are 25 ~ 32 times, how many percent more are girls than boys (the percentage money is reserved for one decimal place) The number of boys is the most in the () times period, and the number of girls is the most in the () times period

|7000-5000|=2000 |9600-7800|=1800 |11000-9200|=1800 |14000-13000|=1000
So 2010 is the closest of the four years
（9200-5000）/5000=84%
The height of sea level is (0), which is different from that of Mount Everest (8844)
（16-13）/13=23.1%
The number of male students in the period of (25 ~ 32 times) is the most, and the number of female students in the period of (25 ~ 32 times) is the most
