MCQ
If $\angle\text{A}=4\angle\text{B} = 6\angle\text{C},$ then $A : B : C?$
A
$6 : 4 : 3$
✓
$12 : 3 : 2$
C
$2 : 3 : 4$
D
$3 : 4 : 6$
✓
Answer
Correct option: B.
$12 : 3 : 2$
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 $12$
$12 : 3 : 2.$
