Answer 2

If the two lights blink together, it will take another 24 seconds for them to blink together again.

Given:

Time taken by a neon light to blink = 6 seconds

Time taken by another neon light to blink = 8 seconds

To Find:

We need to find the time taken by both of them to blink together.

Solution:

Now, since the first light blinks every 6 seconds and another blinks every 8 seconds, we will need to find the LCM of 6 and 8 in order to find the time when they both will blink together

6 = 3 × 2

8 = 2 × 2 × 2

LCM = 3 × 2 × 2 × 2

LCM = 24

Thus, if the two lights blink together, it will take another 24 seconds for them to blink together again.
