|采纳率88%解题思路:假设答对x题,答错的有y题,不答的有z题.
依题意得
,满足6≥x≥0,6≥y≥0,6≥z≥0,且都为整数x+y+z=6① 8x+2z=20②
分x=0时;x=1时;x=2时三种情况讨论.设答对x题,答错的有y题,不答的有z题.
依题意得
x+y+z=6①
8x+2z=20②,满足且6≥x≥0,6≥y≥0,6≥z≥0都为整数
当x=0时,z=10,不合题意舍去;
当x=1时,z=3,y=6,不合题意舍去;
当x=2时,z=2,y=2.
故选D.点评:
本题考点: 三元一次方程组的应用.

先分析得分:11’=4×3‘-1×1’;7‘=3×3’-2×1’;3‘=2×3’-3×1‘
E对4题错1题,AF对3错2,BCD对2错3 (这个贯穿整个分析)
再从高分的入手,比较A、E、F
比较AE,除去不答的①和⑤,只有②同③④⑥反,如②两人都错,则E的③④⑥都对A则全错,与A错2题矛盾.所以②的正解是(+)则F此题错,F与E都还有1题可错
比较EF,因①③同④反,按上面的分析方法可得EF的①③答(-)是正确的,A的③则错
前3题答案已得出,比较AEF的④⑤⑥,此时每人还可错一题.A的④⑥与E都反,必各有1对1错,所以A的⑤为(+)正确,F的⑤错.F的⑤错则F的④(+)正确,与A同对,E错.E的⑤错那么E的⑥(-)则正确,A错.
最后得到题目答案1(-)2(+)3(-)4(+)5(+)6(-)

不生不灭 我的理解是 不在六道中守生 所以 没有六道中的生灭 是一种本源的 恒久不变的状态 是我们自性的状态
但是最近有人跟我解释说 不生不灭 其实也生也灭 只是速度太快 感觉不到 还引用经文 “当处出生,随处灭尽” 加以佐证.这如果是一般人说的 我会嗤之以鼻 但是这种解释好像是出自一位德高望重的法师 我迷惑了 请明白的给个最终解释

|采纳率76.5%您说的是不生不灭,不生当然不灭,但是您举的例子却是有生有灭,有生当然有灭,这不冲突啊.
我不知道这句经文出自何处,建议您先看到原文再说,以免断章取义.
经文如下:
阿难.汝犹未明一切浮尘,诸幻化相,当处出生,随处灭尽.幻妄称相,其性真为妙觉明体.如是乃至五阴六入,从十二处,至十八界,因缘和合,虚妄有生,因缘别离虚妄名灭.殊不能知生灭去来本如来藏.常住妙明,不动周圆妙真如性.性真常中求于去来迷悟生死,了无所得.
它说的并不是人的生灭,而是幻相的生灭,只有到了佛菩萨的境界才能看到物质的生灭,由于速度太快,人看不到,这和您说的是两回事.1年前查看全部

总量=240*80*12=230400m
调走后还剩240*5/6=200人
工作效率提高到12*(1+1/3)=16m/天
每天200*16=3200m
