Question

plzz answer with solution answer 10 and 11​

Answer 1

Ans10. Time interval of first bell=2,4,6..

Time interval of second bell=4,6,8..

Time interval of third bell =6,12,36..

Time interval of fourth bell =8,16,24..

Time interval of fifth bell =10,20,30..

Time interval of sixth bell =12,24,36

So to find interval of time at which they toll together we have to find LCM of these six no.s

So the LCM is 1×2×3×4×5×6=720

So they toll together after 720 minute(12 Hours)
