Analysis of the problem:
The bells toll at intervals of 2, 4, 6, 8, 10, and 12 seconds respectively. To find out how many times they toll together in 30 hours, we need to consider the least common multiple (LCM) of these intervals.

Calculating the LCM:
- LCM of 2 and 4 is 4
- LCM of 4 and 6 is 12
- LCM of 12 and 8 is 24
- LCM of 24 and 10 is 120
- LCM of 120 and 12 is 120
Therefore, the LCM of all the intervals is 120 seconds or 2 minutes.

Calculating the number of times they toll together in 30 hours:
- 30 hours = 30 * 60 * 60 seconds = 108000 seconds
- Number of times they toll together = Total time / LCM = 108000 / 120 = 900 times
Therefore, the bells toll together 900 times in 30 hours.
