Pipes A, B and C are attached to an empty cistern. While the first two can fill the cistern in 4 and 10 hours, respectively, the third can drain the cistern, in 6 hours. If all the three pipes are opened simultaneously when the cistern is half-full, how many hours will be needed to fill the cistern?
\( \frac{90}{11} \)
\( \frac{30}{11} \)
\( \frac{60}{11} \)
\( \frac{120}{11} \)
