If $$\frac{1}{3}$$​A = $$\frac{1}{4}$$​B = $$\frac{1}{5}$$​C, then A : B : C = ?

Correct option is C

Given:

​$$\frac{1}{3} A = \frac{1}{4} B = \frac{1}{5} C$$​

Solution:

Let the common value be k.
Thus, we have:

​$$\frac{1}{3} A = \frac{1}{4} B = \frac{1}{5} C =k$$​​

A : B : C = 3k : 4k : 5k

By dividing each term by k (since k ≠ 0):

A : B : C = 3 : 4 : 5
