If A : B = 6 : 8 and B : C = 5 : 12, then A : B : C is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 15 : 20 : 48.
A : B = 6 : 8 = 3 : 4
B : C = 5 : 12
We have to equal the value of B because B is common
⇒ A : B = 3 : 4 × 5
⇒ B : C = 5 : 12 × 4
⇒ A : B = 15 : 20
⇒ B : C = 20 : 48
So, A : B : C = 15 : 20 : 48
