They next ring together will be at 6:50 a.m.
Step-by-step explanation:
The given is:
We need to know at what time will they next ring together
To solve the problem lets find the lowest common multiple of 10 and 25
∵ The multiples of 10 are 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , 90 , 100 , .....
∵ The multiples of 25 are 25 , 50 , 75 , 100 , ........
∵ The common multiples of 10 and 25 are 50 , 100 , ......
∴ The lowest common multiple of 10 and 25 is 50
∵ The two bells start ringing together at 6 a.m.
∵ The first bell rings every 10 minutes
∴ The first bell rings at 6:10 a.m. , 6:20 a.m. , 6:30 a.m. , 6:40 a.m. ,
6:50 a.m. , .........
∵ The second bell rings every 25 minutes
∴ The second bell rings at 6:25 a.m. , 6:50 a.m. , ........
∴ They start ringing together at 6:50 a.m.
They next ring together will be at 6:50 a.m.
