There are 4 numbers A, B, C, and D. If A:B = 1/2, B:C = 2/7, C:D = 7/3, then A:D will be?  Choose the correct choice from the following answers: A) 1 : 2 B) 2 :1 C) 2 : 7 D) 1 : 7 E) 1 : 3
Solution   A : B = 1 : 2, B : C = 2 : 7, C : D = 7 : 3   âˆ´Aâˆ¶Bâˆ¶Câˆ¶D= 1 : 2 : 7 : 3.   Thus, A : D = 1 : 3   Correct Option 1 : 3
