two trains started simultaneously, at 11:00 am , from delhi to Jaipur moving towards Jaipur and Delhi respectively and cross each others at 3:00 pm. If the train starting from. Jaipur reached its destination 88 minutes before the other train, when did the train starting from Delhi reach Jaipur

(t1 . t2 )^1/2 Is this the formula?

time taken for trains to cross each other = 4hrs = (t1 . t2)^1/2 where t1 = time taken by train 1 to reach jaipur after meeting = t t2 = time taken by train 2 to reach delhi after meeting = t+88 solve to get t = 200 mins so t+88 = 288 mins = 4hrs 48 mins time of arrival = 3pm + 4hr 48 min = 7:48pm

which DILR topic is important for CAT .

Hi, in my experience so far, DILR is pretty volatile in CAT. With the passing years, the difficulty level of the section is only going upwards. After various sessions the only conclusion that I've come to, personally, is that you cannot really focus on a particular topic and expect yourself to do well on the D-day. All the questions are generally an amalgamation of at least 2-3 concepts. So my suggestion would be for you to be consistent with your practice, attempt at least 2-5 sets on a daily basis with varying difficulty.
