Answer 1

Step-by-step explanation:

Hi there ! °• Again at 2 : 54 pm, the 3 tigers will roar together.

Answer 2

$time \: when \: the \: tigers \: will \: roar \: together \\ = 12: 30 \\ duration \: of \: time \: each \: tigers \: roar \: together \\ = 3 \: and \: 6 \: and \: 9 \: mins \\ therefore \: the \: time \: they \: will \: roar \: together \: again \\ = LCM \: of \: 3 \: and \: 6 \: and \: 9 \\ = 18mins$

Hence, they will roar again at 12:48
