Answer 1

Answer:

the time when they beep together fifth times after 5.30 is 11:30 AM

Step-by-step explanation:

3 alarm make beep after 18 24 36 min they beeped together at 5.30 A.M

beeped together at 5:30 AM  

18 = 2 * 3 * 3

24 = 2 * 2 * 2 * 3

36 = 2 * 2 * 3 * 3

LCM = 2 * 2 * 2 * 3 * 3 = 72 min

They will beep together after 72 min

1st beep after 72 min

5th Beep = 72 * 5 = 360 Mins

= 6 hrs

5: 30AM + 6  = 11:30 AM
