three bells ring at intervals of 3,5 and 10 minutes respectively. if they start ringing together at a time, after what time will the next ring together?​

Answer 1

Answer:

to find when three things with different velocities join together, we have to find their lcm.

so lcm of 3,5,10 is 30.so they will ring together after 30 minutes

Three bells rings at the interval of 3,5 and 10 minutes.

To find that if they start ringing together at a timr, after what time will they next ring to ring together:-

Take L.C.M. of 3,5 and 10=2×3×5=30

So after 30 minutes, they will ring together.
