In a certain code language, 'one heading high' is coded as 'CV HJ WS', 'high warnings trip' is coded as 'HJ RF JK' and 'warnings one stakes' is coded as 'JK CV FS'. How is 'trip' coded in that language?

I. 'one heading high' is coded as 'CV HJ WS'. II. 'high warnings trip' is coded as 'HJ RF JK'. III. 'warnings one stakes' is coded as 'JK CV FS'. From statement I and II, we conclude that 'high' is written as 'HJ'. From statement I and III, we conclude that 'one' is written as 'CV'. From statement I alone, we conclude that 'heading' is written as 'WS'. From statement II and III, we conclude that 'warnings' is written as 'JK'. From statement II alone, we conclude that 'trip' is written as 'RF'. From statement III alone, we conclude that 'stakes' is coded as 'FS'. So, we get, 'trip' is written as 'RF'.
