Any idea Pls include reasoning along with all answer posts.

One pendulam ticks 57 times in 58 seconds and another 608 times in 609 seconds. If they start simultaneously, find the time after which they will tick together.

a. 211/19secs
b. 1217/19secs
c. 1218/19secs
d. 1018/19secs

oh sorry not to include the reasoning

the 1st pendulam takes 58/57 sec to tick one time and the 2nd one 609/608 sec. so they both would tick at

lcm of (58/57, 609/608) = lcm of ( 58, 609) / hcf of (57, 608)= 1218/19

hope this helps
