Answer 1

21 kids in party one third have blue eyes.its means that 7 kids have blue eyes and 14 kids have not blue eyes

Answer 2

Total number of kids = 21

Number of kids which have blue eyes = one third of 21
  
                                                             = 21/3
                                                             
                                                             = 7

Number of children who do not have blue eyes = 21 - 7 
                                                  
                                                                           = 14
