If 7A = 4B = 14C, then what is A : B : C?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 4 : 7 : 2.
Given:
7A = 4B = 14C
Explanation:
According to the given question,
A : B = 4 : 7
And B : C = 14 : 4 = 7 : 2
Now, A : B : C = (4 × 7) : (7 × 7) : (7 × 2) = 28 : 49 : 14
⇒ A : B : C = 4 : 7 : 2
Hence the required answer is 4 : 7 : 2.
