 這真的是國中數學嗎~                                                                         
答案真的讓我目瞪口呆

考考您~~                                                                                 
已知:媽媽比小孩大 21歲,而6年之後媽媽的年齡是小孩年齡的5倍。 請問:爸爸現在在哪裡?                                                                     
先不要看下面的解答,好好想一想,這是國中數學的東西~

請注意它是問現在爸爸在哪裡........                                                         
  

 

 

 

 

 

                                                                                       
參考解答:解聯立:                                                                           
                                                                                           
設媽媽M 歲,小孩 C 歲                                                                      
M = C +21                                                                                  
M+6 = (C+6)*5                                                                              
=> C + 21+ 6= ( C+ 6 )*5                                                                    
=> C + 21+ 6= 5C+ 30                                                                        
=>  21+ 6 -30 = 5C- C                                                                       
=>  - 3 = 4C                                                                                
解聯立後: C = - 3/4                                                                         
                                                                                           
也就是說小孩子在九個月之後會出生                                                           

 

                                                                                       
所以,爸爸現在在媽媽上面! ...................                                             
  ......................................................水喔! *_*
