In two months, the legal minimum wage in the country of Kirlandia will increase from five Kirlandic dollars(KD5.00) Per hour to KD5.50 per hour. Opponents of this increase have argued that the resulting rise in wages will drive the inflation rate up. In fact its impact on wages will probably be negligible, since only a very small proportion of all Kirfandic workers are currently receiving less than KD5.50 per hour.
既然是大牛,请教一下,此题怎解?多谢阿!230,有点不懂
DS: s/q是一个整数,那么s/q是一个偶数吗?
1). s是4的倍数
2). q是4的倍数
如果(1)s是4的倍数,加上s/q是一整是一个整数,此时因为不能符合(2)条件,应该q不能是4数的倍,那么s/q必是一偶数阿!
如果(1)考虑"q是4的倍数"的情况下,就可能得不出答案,但不该排除(2)的条件来考虑吗?
很困扰我阿!

好心的大牛,
我的纠结点就在既然(2)提了"q是4的倍数",那(1)的q还能用"4的倍数"的条件加以判断么?
如果用了(1)条件,又用了"q是4的倍数",等於是用了(C)选项,这样还能用来判断(A)答案是否正确么?
