What should be the minimum no. of trains, if the trains are traveling at 40kmph and a regular interval of 6mins is to be maintained b/w the departure of two trains from both the stations?

    a. 31 b. 30 c. 62 d. 63 e. None of these 2. A and B can each run at a uniform speed along a circular track. To cover the whole track, A need 5

    seconds less than B. If they start simultaneously from the same place and run in the same direction, they meet 30 seconds later. At how many points will they meet if they run in the opposite directions?

    a. 9 b. 12 c. 13 d. 16 e. None of these 3. A man leaves office daily at 7pm, when a driver comes to pick him up from his home. One day he gets

    4. Two buses B1 and B2 start from A and B respectively towards each other. B2 departs 30mins after B1

    does. B1, after traveling for 2 hours, is separated from B2 by 19/30th of the distance betweenw A and B. If B1 reaches B half hour later as compared to when B2 reaches A, how much time will each take to cover the distance?

    5. A woman is walking down a downward-moving escalator and steps down 10steps to reach the bottom.

    S's steps. A gets to the top of the escalator after having taken 30 steps while S, because of his faster pace, ends up taking 40 steps to reach the top. If the escalator was turned off, how many steps wud they have to take to walk up?

    CopyCats- Total Gadhas National Online Mock CATs

    For the last two years, TotalGadha.com has been known and appreciated for quality content. Last year, when we conducted our CopyCATs (Indias first national online mock cats), the response was no different- many of our mockcat users complimented us for creating tests that were original, tricky, and very realistic. No wonder, we had extremely good results in terms of IIM Calls. More than 100 of our CopyCat users got placed in top 10 MBA institutes. This year, we are again going to start with our CopyCATs from 26th July, 2009. But unlike last year, we are offering our CopyCATs only to our CAT CBT Club members. Why only to our CBT Club members? Because we believe that only test-taking will not guarantee the result of our CopyCAT users. We want them to crack CAT so that we can proudly claim that we helped them along the way. Therefore, we will also provide them with a lot of extra material to bolster their preparation. What would our CopyCAT users get in CAT CBT Club? As a privilege member of this club, you would be getting

    9 national online mocks- with percentiles and cutoffs. The test would be taken by nearly 10000+ users. As TG users are highly serious students, your percentiles will be highly authentic.

    30 sectional tests- When you are bored of taking long sectional tests, take these sectional tests to master a particular section.

    50 mini-quizzes- small quizzes (with 5 questions each) for parajumbles, paracompletion, RC, quant and DI. Small intensive doses.

    Video lessons- The biggest advantage of TG.com. We have started uploading one video lesson on important topics everyday. Just watch them and learn the fundas that you couldnt find in the classrooms. In short, personal tutoring by Total Gadha.

    Interactive lessons- Lessons in which you cannot proceed further unless you give the correct answer. This forces you to solve a question and learn.

    Problem-solving forums- Just like the main forums on TG.com, we have forums inside the CAT CBT Club with none of the junk and clutter found in the main forums. Here it is no nonsense problem-solving and discussion. Plain and simple.

    Personal counselling from TG and Dagny with constant monitoring and guidance. How much is the membership fee for the CAT CBT Club and how long is the membership for? The membership fees is $22 and the membership is valid for six months. How can I make a payment? The payment is through Credit Card. You would get an access to the CBT section within minutes of your payment. Rest assured, the payment is through safe mode. If you do not have a credit card, send us a cheque for Rs 1000 in the name of 'LA Edukreation Pvt Ltd.' to 'LA Edukreation Pvt. Ltd., E- 225, First Floor, G.K.- 1, New Delhi- 110048' along with your email-id. We will make the payment in your name with our credit card.
