How to crack TCS written test:

Many of your friend says that if you want to clear the Aptitude Round, then you must attempt somewhere around 25 -28 questions to make it through. But this is not the case. What I figured out was that TCS is selecting candidates based on their accuracy. I attempted just 21 questions and still made it through, because around 18 questions Ianswered were correct. I made less guess. I think is based on accuracy & atleast you have to do 17 questions in 60 mins.
Please do not guess or do not attempt if you are not sure about your answer
Please do not try to cheat because question seem to be same in your neighbour computer but value in questions are change so option gets change.

1. Alok and Bhanu play the following min-max game. Given the expression N = 19 + X * (Y - Z), where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be

7. Alice and Bob play the following coins-on-a-stack game. 100 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack. Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (for some i between 0 and 100). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2- move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coin is the third coin from the top. Then
O In order to win, Alice's first move can be a 0-move or a 1-move.
O In order to win, Alice's first move should be a 1-move.
O In order to win, Alice's first move should be a 0-move.
O Alice has no winning strategy.

Zeus and Poseidon had been rivals for the hand of Thetis until Prometheus, the fire-bringer, warned Zeus of a prophecy that Thetis would bear a son greater than his father. For this reason, the two gods withdrew their pursuit, and had her wed Peleus. The following statement is another interesting prophecy about the ages of two childen of Zeus that would hold true at some time during the lifetime of the children. 4 years ago, Athena's age was twice Helen's age. 4 years hence, Athena's age will be 4/3 times the age of Helen.

In the experiment, a person makes a journey into space at nearly the speed of light and comes back to earth. He finds that he has aged five times less than his twin who stayed back on earth for 40 years. This is popularly known as the Twin Paradox. Now, consider the case of Hansel and Gretel, who are not twins. 9 years ago, Hansel was twice as old as Gretel. If they journey into space, an atomic clock assists in logging the start time of their journey accurately. If they do not journey into space, 9 years hence, Hansel's age will be 413 times the age of Greters. Find Hansel's age today in binary numbers.

Each lichen grows approximately in the shape of a circle. The relationship between the diameter of this circle and the age of the lichen can be approximated with the formula: d =5* (t -12) for t >12, where d represents the diameter of the lichen in millimeters, and t represents the number of years after the ice has disappeared. Using the above formula, calculate the diameter of the lichen, 49 years after the ice has disappeared.

In studying the brains of Alzheimer and non-Alzheimer patients it has been found that those diagnosed with Alzheimers have less brain tissue compared to non-Alzheimer patients. The results show a correlation between a decrease of brain tissues with an increase in abnormal protein deposits in the brain. Therefore one hypothesis for the cause of Alzheimers is due to the abnormal protein deposits. Which of the following weakens the conclusion above?
O Autopsies of Alzheimer patients have shown that deterioration of intellectual faculties is often associated with emotional disturbance and personality changes.
O The brains of Alzheimer patients have been found to produce an unusual substance which decomposes protein.
O People who are in their sixties are more likely to develop Alzheimers than any other age group.

28)Amal bought 5 pens, 7 pencils and 4 erasers. Rajan bought 6 pens, 8 erasers and 14 pencils for an amount which was half more than what Amal had paid. What % of the total amount paid by Amal was paid for pens?
sol) Let, 5 pens + 7 pencils + 4  erasers = x  rupees
so 10 pens  + 14 pencils + 8 erasers = 2*x rupees
also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees
so (10-6) = 4 pens = (2-1.5)x rupees
so 4 pens = 0.5x rupees => 8 pens = x rupees
so 5 pens = 5x/8 rupees  = 5/8 of total (note x rupees is total amt paid by
amal) i.e 5/8 = 500/8% = 62.5%
29)A work is done by 2 people in 24 min. One of them can do this work alone in 40 min. How much time required to do the same work for the second person?
sol)Two people work together in 24 mins.
So, their one day work is
(1/x)+(1+y)=(1/24)
One man can complete the work in 40mins
one man's one day work (1/y)= (1/40)
Now,
(1/x)=(1/24)-(1/40)
(1/x)=(1/60)
So, x can complete the work in 60 mins
30)A man has to get air-mail. He starts to go to airport on his motorbike. Plane comes early and the mail is sent by a horse-cart. The man meets the cart in the middle after half an hour. He takes the mail and returns back, by doing so, he saves twenty minutes. How early did the plane arrive?
sol)10min:::assume  he started at 1:00,so at 1:30 he met cart .He returned home at 2:00.so it took him 1 hour for the total jorney.by doing this he saved 20 min.so the actual time if the plane is not late is 1 hour and 20 min.so the actual time of plane is at 1:40.The cart travelled a time of 10 min before it met him.so the plane is 10 min early.

22. Any serious policy discussion about acceptable levels of risk in connection with explosions is not well served if the participants fail to use the word “explosion” and use the phrase “energetic disassembly” instead.

Therefore, of the two terms, “explosion” is the one that should be used throughout discussions of this sort.

Which of the following is an assumption on which the argument above depends?

(A) In the kind of discussion at issue, the advantages of desirable reactions to the term “explosion” outweigh the drawbacks, if any, arising from undesirable reactions to that term.
(B) The phrase “energetic disassembly” has not so far been used as a substitute for the word “explosion” in the kind of discussion at issue.
(C) In any serious policy discussion, what is said by the participants is more important than how it is put into words.
(D) The only reason that people would have for using “energetic disassembly” in place of “explosion” is to render impossible any serious policy discussion concerning explosions.
(E) The phrase “energetic disassembly” is not necessarily out of place in describing a controlled rather than an accidental explosion
