Hi guys,
Until last year I was undecided for appearing for CAT. I appeared for CAT'15 without any preparation ( I didn't even know that there were supposed to be 3 sections). Therefore , it wasn't a surprise that I found CAT to be very difficult. I ended up scoring 88 %ile with 99.2 + in VARC, and 60-67 in both Quant and DILR. This time though I wish to appear for CAT with full preparation.
I had estimated my quant to be fairly strong, since I have cleared IIT-JEE and Regional Maths Olympiad. But CAT'15 put me back to my place. I have started solving the Time quant material. Do you guys thing this will suffice for the preparation??
A and B are moving on a circular track in a direction opposite to which C is running.C is moving twice and thrice the speed at which A and B are running respectively.they start running from the same point.It is known that A's average speed is 3m/s and track is 120m in length. When will B after start find himself equidistant between A and C for the first time?
Please mention the approach.
A railway track runs parallel to a road and a cyclist whose speed is 12k/h , meets a train at the crossing everyday at the same time. One day, the cyclist started 25 min late and met the train 6km ahead of the railway crossing. What is the speed of the train?
Mention the approach pls
