The given K map for function G = 

       A'B'  A'B  AB  AB'

 C'D'                    

 C'D               1     

 CD                1     

 CD'               1     

 The given K map for function H = 

       A'B'  A'B  AB  AB'

 C'D'                    

 C'D          1    1     

 CD                1     

 CD'               1     

 The solution for  G is

 G = ABC + ABD

 The solution for H is

 H = BC'D + ABC
