The sum of all the solutions of the equation

\cos x \cdot \cos \left(\frac{\pi}{3}+x\right) \cdot \cos \left(\frac{\pi}{3}-x\right)=\frac{1}{4}, x \in[0,6 \pi]

View answer and explanation

Correct option: C

\frac{110 \pi}{3}

None of the options are correct. The sum of all solutions is

30\pi

, so Option D (None of these) is correct.
