✍Your answer⬇⬇⬇⬇
Given: 6 bells commence tolling together and toll at intervals of 2,4, 6,8,10,12.
To find least time after each bells rings together we find L.C.M. of 2,4,6,8,10,12.
As;
2= 2×1
4=2×2
6=2×3
8=2×2×2
10=2×5
12=2×2×3
So, L.C.M. of 2,4,6,8,10,12= 2×2×3×5= 120
So, after each 120 minutes or 2 hours all 6 bells rings together.
So,
In 30 hours they will rings 15 times. But they also rings together at starting.
Therefore,
Total number of times they will rings together= 15+1= 16
Hope it helps
