.__________.______________________________________. A x C (100 - x) B Let AC = x km. Then, CB = (100 -x) km.
I. AB = 125% of CB 100 = 125 x (100 - x) 100 100 - x = 100 x 100 = 80 125 x = 20 km. AC = 20 km. Thus, I alone gives the answer.
II. AC = 1 CB 4 x = 1 (100 - x) 4 5x = 100 x = 20. AC = 20 km. Thus, II alone gives the answer. Correct answer is (C).
