Question

In a firing range, 4 shooters are firing at their respective targets. The first, the second, the third and the
fourth shooter hit the target once in every 5s, 6s, 7s and 85 respectively (s = seconds). If all of them hit
their target at 9:00 a.m., when will they hit their target together again?​

Answer 1

Answer:

The question can be done by taking the lcm of all time

So lcm is 5×6×7×17(taking 5 common between 5 and 85)

3570 secs

They will meet at 9:59:30

Hope the answer is correct

Answer 2

L.C.M of 5,6,7,8 is =

840 s

so, 840s = 840/60 =14m

so, again they will hit the target together at 9:14a.m

hope this is helpful
