Answer 2

Given

One neon light blinks every 4 seconds

The other blinks every 6 seconds.

To find

In 60 seconds, how many times will they blink at the same time

Solution

One neon light blinks every 4 seconds

The other blinks every 6 seconds.

Therefore we find the LCM of 6&4.

LCM=12.

Therefore to find the no of times it will blink at the same time in 60s

=60/12

=5

In 60 seconds they blink 5 times at the same time.
