Given :

Beep Duration of first device \(=60\) seconds

Beep Duration of Second device \(=62\) seconds

To find the interval of beeping together, we need to find the LCM of 60 and 62 first.

\(60=2 \times 2 \times 3 \times 5\) \(62=2 \times 31\) LCM \(=2 \times 2 \times 3 \times 5 \times 31=1860\) seconds

Convert time into min

\(160 \mathrm{sec}=\frac{1860}{60} \mathrm{mins}=31 \mathrm{~min}\)

electronic devices will beep after very 31 minutes.

hence, both device will together again beep at \(10: 31\) am again.
