What are the quiz scores:

one quiz score is six more than the other quiz score

Let x and (x+6) represent the two quiz scores

Question states*** average of two quiz scores is 81. 

 [x +(x+6)]/2 = 81

  2x+6 = 162

   2x = 156

    x = 78  The quiz scores are 78  and 84

  (78 + 84)/2 = 162/2 = 81
