On a certain internet polling, the rejection rate of Bru Exotic production was 4% , for Bru Classic production 8% and for both the coffee varities combined was 7%. What was the ratio of Bru exotic to Bru classic production

• let x be production of bru exotic,y be production of bru classic
  rejection of x+rejection of y =rejection of (x+y)
  4*x/100+8*y/100=7*(x+y)/100
  x/y=1/3
