If (1/3)A = (1/4)B = (1/5)C. Then A : B : C is  Choose the correct choice from the following answers:
A) 4 : 3 : 5
B) 5 : 4 : 3
C) 3 : 4 : 5
D) 20 : 15 : 12
E) None of these
(A/3) = (B/4) = (3 : 4 : 5/5) = K   =&gt; A = 3K, B = 4K, 3 : 4 : 5 = 5K   Therefore, A : B : 3 : 4 : 5 = 3K : 4K : 5K = 3 : 4 : 5   ANSWER:3 : 4 : 5
