1.一个三位数,各位之和为16,十位数字大小等于个位与百位之和.若个位与百位上的数字交换,得到的数比原数大594,求原数.
设下各位数分别是x,y,z然后列下方程解就好,首先得到十位上是8,接着交换后的数减原数为594,可知个位与百位之差为5+1=6,最后答案187
2.如果a #b=(3×b)那么2+(2×a) #(3 #5)的值是47
3.某镇受流感影响,第一个月20%的人病倒了,还有80%的人健康着,第二个月20%得病的人痊愈了,还有20%原本健康的人受感染了,求第二个月健康人口的比例
(80*(1-0.2)+20*0.2)/100=68%
4.抽屉里有28件T恤,6件红的,5件蓝的,其余为白色,如果Bob度假前理行李随机拿T,他至少要从抽屉中拿几件才能保证他有三件相同颜色的T?
7件
5.一个家具工厂生产各种家具,已知每个工人每天能生产2个桌子或6个凳子,共有21名工人,一套家具包括1个桌子和4个凳子,问,应怎样安排工人工作才能使生产的家具都成套?
2x:6y=1:4,又x+y=21,得9人生产桌子,12人生产凳子
6.四娃Pat,Sean,Alan,Sam都在今天办生日会,再过一年Sam就跟Pat现在的岁数一样了,Alan的岁数是Sean的一半,且比Sam小三岁,Sam今年11岁,问Sam15岁的时候Alan几岁?
Alan比Sam小3岁,所以Sam15岁,Alan12岁.
