If $$\frac{1}{3}$$​ of A = $$\frac{3}{4}$$​ of B = $$\frac{1}{6}$$​ of C, then what is A : B : C?

Correct option is C

Given:

​$$\frac{1}{3}A = \frac{3}{4}B = \frac{1}{6}C$$​

Solution:
Let the common value be x.

Then,

​$$A = 3x, \quad B = \frac{4}{3}x, \quad C = 6x$$​​

A : B : C = $$3x : \frac{4}{3}x : 6x = 9 : 4 : 18$$ (multiplying all by 3)
