Question
- Four bells commence tolling together. They toll at intervals of 2, 2, 4 and 2 seconds respectively. After what time will they toll together again. 3
Solution
The question is asking for the time when all four bells will toll together again. This is essentially asking for the least common multiple (LCM) of the tolling intervals, which are 2, 2, 4, and 2 seconds.
Here are the steps to find the LCM:
- List the numbers: 2, 2, 4, 2
- Since all the numbers are the same or multiples of each other, the LCM is simply the largest number, which is 4.
So, the bells will toll together again after 4 seconds.
