Question
Dear Ms.Janet,

I need your help yet again,

The number of cartons of juices to the number of cartons of milk to the number of cartons of soft drinks is in the ratio of 12 : 5 : 1. There are 66 more cartons of juices than soft drinks. How many cartons of milk are there?

Answer
C = total cartons of all drinks
juice:milk:softdrinks = 12:5:1

cartons of juice = 12·C/(12+5+1) = 2C/3
cartons of soft drinks = 1·C/(12+5+1) = C/18

"There are 66 more cartons of juices than soft drinks."
2C/3 = C/18 + 66
C = 108

cartons of milk = 5·C/(12+5+1) = 5·108/18 = 30
