Answer is 2.40 am .


Lcm (4,25,48) =1200 sec.

1200/60 = 20 min.

2.20 am + 20min =2.40 am.

The traffic lights at three different circles change after 4 seconds, 25 seconds, 48 seconds. If they all change simultaneously at 2:20 am, then they will again change simultaneously at

(a) 2.30 a.m.
(b) 2.40 a.m.
(c) 2.50 a.m.
(d) 3.00 a.m.

LCM Of 4,25,48 is 1200. i.e, after 1200 seconds (20 minutes) they will change simultaneously.
So 2:40 am is the right answer.
