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. In fact, the word “explosion” elicits desirable reactions, such as a heightened level of attention, whereas the substitute phrase does not. 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 23.

Q. 32. 2 trees are there. One grows at 3/5 of the other. In 4 years total growth of the trees is 8 ft. what growth will smaller tree have in 2 years. Sol) THE BIG TREE GROWS 8FT IN 4 YEARS=>THE BIG TREE GROWS 4FT IN 2 YEARS.WHEN WE DIVIDE 4FT/5=.8*3=>2.4 ans: 1.5 mt 4 (x+(3/5)x)=88x/5=2x=5/4 after 2 years x=(3/5)*(5/4)*2 =1.5 Q. 33. There is a six digit code. Its first two digits, multiplied by 3 gives all ones. And the next two digits multiplied by 6 give all twos. Remaining two digits multiplied by 9 gives all threes. Then what is the code? sol) Assume the digit xx xx xx (six digits) First Two digit xx * 3=111 xx=111/3=37 ( first two digits of 1 is not divisible by 3 so we can use 111) Second Two digit xx*6=222 xx=222/6=37 ( first two digits of 2 is not divisible by 6 so we can use 222) Thrid Two digit xx*9=333 xx=333/9=37 ( first two digits of 3 is not divisible by 9 so we can use 333) Q. 34. There are 4 balls and 4 boxes of colours yellow, pink, red and green. Red ball is in a box whose colour is same as that of the ball in a yellow box. Red box has green ball. In which box you find the yellow ball? Ans is green... Sol) Yellow box can have either of pink/yellow balls. if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball in the yellow box have same colour) thus this possibility is ruled out... therefore the ball in yellow box must be pink,hence the colour of box containin red ball is also pink.... =>the box colour left out is "green",,,which is alloted to the only box left,,,the one which has yellow ball.. Q. 35. A bag contains 20 yellow balls, 10 green balls, 5 white balls, 8 black balls, and 1 red ball. How many minimum balls one should pick out so that to make sure the he gets at least 2 balls of same color. Ans:he should pick 6 ball totally. Sol) Suppose he picks 5 balls of all different colours then when he picks up the sixth one, it must match any on of the previously drawn ball colour. thus he must pick 6 balls Q. 36. What is the number of zeros at the end of the product of the numbers from 1 to 100 Sol) For every 5 in unit palce one zero is added Ch eta naS so between 1 to 100 there are 10 nos like 5,15,25,..,95 which has 5 in unit place. Similarly for every no divisible by 10 one zero is added in the answer so between 1 to 100 11 zeros are added for 25,50,75 3 extra zeros are added so total no of zeros are 10+11+3=24 Q. 37. 10 Digit number has its first digit equals to the numbers of 1's, second digit equals to the numbers of 2's, 3rd digit equals to the numbers of 3's .4th equals number of 4's..till 9th digit equals to the numbers of 9's and 10th digit equals to the number of 0's. what is the number?.(6marks) Ans:2100010006 2shows that two 1's in the ans 1shows that one 2 in ans 0shows no 3 in the ans 0shows no 4 in the ans 0shows no 5 in the ans 1shows one 6 in the ans 0shows no 7 in the ans 0shows no 8 in the ans 0shows no 9 in the ans 6shows six 0's in the ans Q. 38 A and B are shooters and having their exam. A and B fall short of 10 and 2 shots respectively to the qualifying mark. If each of them fired atleast one shot and even by adding their total score together, they fall short of the qualifying mark, what is the qualifying mark? Ans is 11 coz each had atleast 1 shot done so 10 + 1 = 11 n 9 + 2 = 11 so d ans is 11 Q. 39 Gavaskar average in first 50 innings was 50. After the 51st innings his average was 51 how many runs he made in the 51st innings Ans) first 50 ings. run= 50*50=2500 51st ings. avg 51. so total run =51*51=2601. so run scored in that ings=26012500=101 runs. Q. 40. Anand finishes a work in 7 days, Bittu finishes the same job in 8 days and Chandu in 6 days. They take turns to finish the work. Anand on the first day, Bittu on the second and Chandu on the third day and then Anand again and so on. On which day will the work get over? a) 3rd b) 6th c) 9th d) 7th Ans is d) 7th day Sol) In d 1st day Anand does 1/7th of total work similarly, Bithu does 1/8th work in d 2nd day hence at d end of 3 days, work done = 1/7+1/8+1/6=73/168 remaining work = (16873)/168 = 95/168 again after 6 days of work, remaining work is = (9573)/168 = 22/168 and hence Anand completes the work on 7th day.(hope u understood.)

Either complaining about the US or expressing an attitude that your culture is superior can cause Americans to take offence. Americans do possess a great deal of culture arrogance, and think that their way is the only right way. They think that the US is the best place on earth, otherwise why would everybody by trying to get here? Whether you agree or not, remember that you are a guest in the US and it would be rude for a guest to insult his host 15.

But it is at times interpreted as a hindering factor for development. This happens because population is both a consumer and producer. There are two schools of thought. One which treats population as a resource, and the other as a burden to the society. The truth, in fact, lies somewhere in between. The interplay of factors responsible for population growth and those for development decide the resourcefulness of population. 20. Why is it said that population is one resource that never depletes? 1) because other resources deplete 2) because population is an everincreasing phenomenon Answer 3) because population is seen as a resource 4) because it is an easily available commodity 5) None of these 21. Why population is at the same time treated as a resource and also as a burden to the society? 1) because population is the creator and at the same time it is also the user Answer 2) because a less number of people are engaged in production and a large number of people are dependent on it 3) because population is not always a producer but it is always a consumer 4) when the growth of population is checked it is a resource and when it increases rapidly it is burden to the society 5) None of these 22.

Re: TCS Off Campus Exam Placement Papers
The questions asked in the placement papers of TCS are: Q1)Given a collection of points P in the plane , a 1set is a point in P that can be separated from the rest by a line, .i.e the point lies on one side of the line while the others lie on the other side. The number of 1sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position (.i.e no three points in P lie on a line) is a)3 b)5 c)2 Q2) Paul the octopus who has been forecasting the outcome of FIFA world cup matches with tremendous accuracy has now been invited to predict ICC world cup matches in 2011. We will assume that the world cup contenders have been divided into 2 groups of 9 teams each. Each team in a group plays the other teams in the group. The top two teams from each group enter the semi finals ( after which the winner is decided by knockout). However, Paul has a soft spot for India and when India plays any team, Paul always backs India. Alas, his predictions on matches involving India are right only 2 out of 3 times. In order to qualify for the semi finals, it is sufficient for India to win 7 of its group matches. What is the probability that India will win the ICC world cup? a)(2/3)^10 b)(2/3)^9 + 8/3 * (2/3)^9 c)8/3 * (2/3)^9 d)(2/3)^10 + 8/3*(2/3)^9 Q3) A toy train produces at least 10 different tunes when it moves around a circular toy track of radius 5 meters at 10 meters per minute. However , the toy train is defective and it now produces only two different tunes at random. What are the odds that the toy train produces 4 consecutive music tunes of the same type? a)1 in 16 b)1 in 4 c)1 in 8 Q4) A number when divided by D leaves a remainder of 8 and when divided by 3D leaves a remainder of 21 . What is the remainder left, when twice the number is divided by 3D? a)13 b)cannot be determined c)3 d)42 (solution:c) Q5)Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who gets to first cut and have a piece of the cake. One friend suggests that they have a blindfold friend choose from well shuffled set of cards numbered one to six. You check and find that this method works as it should simulating a fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and throwing a die. You note that the number shown by the method of picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total would be likely to appear more often – 8,9 or 10? a)8 b)All are equally likely c)9 d)10 TCS Placement Papers
