I think the ratio of Resistances of AB:BC:CA might be 3: 4: 5.As resistance is directly proportional to the length of the wire .

Sorry Poonam, you forgot to consider those segment which are in parallel to each individual segment.
 
To answer such question, always remember to evaluate the effective resistance for each and every segment.
 
Thus, evaluating the effective resistance in each segment of the set-up, we get, 
RAB : RBC : RCA = 27/12 : 32/12 : 35/12 = 27 : 32 : 35
