Question

Six bells commence tolling together and toll at intervals 2,4,6,8,10 and 12 seconds respectively.In 30 minutes, how many times do they toll together

Answer 1

Answer:

5 times

Step-by-step explanation:

first first of all you need to find the LCM of 2 ,4 ,6 ,8 ,10 and 12 which is 360

after 360 seconds or 6minutes they will toll together first

so in 30 minutes they will toll 30/6 times

that is 5 times
