Answer 2

Answer:

12 second

Explanation:

First mobile rings = 3 second

second mobile rings = 4 second

To find when both mobiles ring at same time.

We have to find the LCM of 3 and 4. Because 3 and 4 both are not divided by any number, so LCM will be 3×4 = 12

Hence both phone rang at every 12 seconds same time.
