Answers
Given : Three babies A, B, C cry out at every interval of time.
Baby A cries every 20 minutes,
B cries out every 30 minutes
C cries at every 40 minute.
they are observed at the same time
To Find : after what time will they cry at the same time
Solution:
To Find the time at which they cry at the same time need to find LCM
of 20 , 30 and 40
20 = 2 x 2 x 5
30 = 2 x 3 x 5
40 = 2 x 2 x 2 x 5
LCM = 2 x 2 x 2 x 3 x 5
= 120
After 120 minutes or 2 hrs they cry at the same time
