※ 引述《murai111 (明鏡止水)》之銘言： : A parallelogram diagram is given whose length is 9 and breath is 6 and : the angle between the breadth and length is given as ‘x’ degrees : (x degrees is greater than 90). : Col A: Area of the parallelogram : Col B: 50 : 我寫D 不知大家意見我覺得是D : Given 'k' and 'm' as two numbers whose LCM is 'km' & 'm' and 'n' are : two numbers whose LCM is 'mn'. If k, m, n > 0 : Col A: LCM of 'k' and 'n' : Col B: 'kn' : 還是D 不太確定應該是D [k,n]<=kn : Given range of 'n' numbers as 9.5 and the range of 'q' numbers as 21.5. : If the two lists are combined then range of (n+q) numbers? : (It is also given that the numbers in the two lists are different : and in increasing order) range應該大於等於31吧如果兩個list都沒有一樣的數 : Given that the number of architects in an organization is 1/4 of the : total and the organization hired 60 more persons of which 50 are : architects and after which the ratio of architects increased from : 1/4 to 1/3. Find the number of people in the organization if none of : them have gone out of the organization? : 答360? same here! : 13. A right angled triangle ABC is given whose sides have been extended : to form three squares. : Col A: Area of square formed by hypotenuse. : Col B: sum of areas of squares formed by other two sides : 不確定題意我答 C C沒錯 a^1+b^2=c^2 : 14. If an amount of 40,000 is split and invested, one portion at 4.5% : and the remaining at 6% and if the cumulative interest at the end of : 1 year is 1890(not sure) then : Col A: Interest yielded by the portion with 4.5% : Col B: xxx (some number) : 不太懂雖然她題目也不是很確定要列式的話應該是 0.06x + 0.045*(40,000-x) = 1980 吧 (如果此利率是單期利率且只有一期的情況下) : 15. There are 'x' boxes and the balls are arranged in such a way that : no ball is remained. If the number of boxes is reduced by 3 and if : 12 balls are arranged in them, then 5 balls are left behind. : What is the original number of boxes 'x'? : A. 8 : B.14 : C.26 : D.31 : E.34 : 不太會... 我也不是很懂題目的意思目前的理解是在某種分法之下 17顆球分給x個箱子可分盡若箱子減少三個則剩下5顆球..??? @@ -- http://www.wretch.cc/album/berryberry -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.224.36.53
