MCQ

If $\angle\text{A}=4\angle\text{B} = 6\angle\text{C},$ then A : B : C?

A
6 : 4 : 3
B
12 : 3 : 2
C
2 : 3 : 4
D
3 : 4 : 6

Answer

12 : 3 : 2
Solution:
Let A be x
$\text{B}=\frac{1}{4}\text{x}$
$\text{C}=\frac{1}{6}\text{x}$
A : B : C
$\text{x}=\frac{1}{4}\text{x}:\frac{1}{6}\text{x}$
LCM of 4 and 6 is 12
12 : 3 : 2.
