猴哥GRE数学难题112题第11是什么意思,求破!
一个货币市场上个月共结余48000（美元~哈哈）,用它赚了360的利息,问以年单利计算每年利率是多少?
360*12/48000=9%
——文字直译：某一货币市场户口上月整个月的结余为48000,而月内获得利息360,这户口上月的年单利率为多少?
再问： лл����ʵ������n= (k+(r/s)) / (t/v)in the equation above, k, r, s, t, and v represent positive numbers. Multiplying which one of these numbers by 2 will reduce the value of n to 1/2 of its present value
再答： �� n = (k+(r/s)) / (t/v) �����ϵģ��������ʽ�У�k�� r�� s�� t �� v ��ʾ������Щ�����е��ĸ�������� 2 ����ʹ n �� 1/2 [�ģ��֣�ֵ����n] ѡ��A:k B:r C:s D:t E:v ����������Ϊ ѡ�� D. t ��˼���ǣ��ĸ������ 2 ��ʹ n ��� n/2 ��
