The time at which the three bells will toll together will be LCM of 0.25 ,0.1 ,0.125.
Because LCM is least common multiple so LCM will give us the time at which the three bells rings.
LCM of :-
X=0.5 y=0.1 z=0.125
Multiply x ,y and z by 40 , to convert decimal into whole no.
So,
LCM of (40x,40y,40z)=LCM of (10,4,5)
So LCM of 10,4,5 is 20 that is equal to LCM of 40×(x,y,z)
So,LCM of x,y,z is 20/40=0.5
So ,LCM is 0.5
Therefore ,the bells will toll again after 0.5 second.
