Susanna's average score on all exams was 88. On Greek exams it was 80, and on Latin exams 92. What is the ratio of the number of Greek exams to the number of Latin exams?

• Let no.of greek exams=x,latin=y
  80x+92y=88(x+y)
  x/y=1/2

• all the exams were either greek or latin. let number of Greek exams= x and number of latin exams=y. score of all exams/(x+y)=88, score of all exams = (x+y)*88.
  score of greek exams/(x)=80, score of greek exams= x*80. score of latin exams/(y)=92, score of latin exams= 92*y.
  
  score of all exams = score of latin exams + score of greek exams
  88x + 88y = 80x + 92y
  8x=4y
  x:y=2:1.
