Answers
Given : planned 16 minutes for Kanab. 24 minutes for Amab and 30 minutes for Pranav to walk around the circular mall continuously .
Started at 10 AM
To find : At what time will all of them meet again at starting point
Solution:
Kanab - 16 minutes
Amab = 24 minutes
Pranav - 30 minutes
Find LCM of all the times to get , the the time they will meet again
16 = 2 * 2 * 2 * 2
24 = 2 * 2 * 2 * 3
30 = 2 * 3 * 5
LCM = 2 * 2 * 2 * 2 * 3 * 5
= 240 minutes
= 4 hrs
They started at 10 AM so they will meet at 2 PM
They are doing social work to save environment
