  • TCS SAMPLE QUESTIONS For student’s preparation(New Test Pattern 2010 onwards)
  • TCS pattern since year 2010 haschanged. From this year onwards the newpattern has been followed .In the newpattern 35 questions have to be answeredin 60 minutes time. However thesignificant difference is that the Englishpart (verbal, synonyms) has been deletedin the new test pattern; though readingcomprehension is likely to continue – thetest is named “TOUCHSTONE”.
  • Some notable points TCS test is computer based test. Each student will get unique questions – as random questions will pop-up- on computer screen - so do not copy. There will be negative marking – so do not guess. Answer the question only if you are more than 80% sure of the correctness of the answer. You are allowed to use calculators, but not mobile phones. Carry HB pencils, eraser, coloured pencils etc. for answering analytical reasoning questions – rough work.
  • In the new test pattern questions are equally divided amongst the three/ four types as listed below:a) Quantitative Ability about 15 questions.b) Logical Reasoning about 10 questions.c) Analytical Reasoning about 5 questions.d) Reading comprehension about 5 questions.
  • Some sample questions arediscussed in this presentationto facilitate the preparation ofstudents. First let us take thequantitative questions whichcan be typified to some extent.
  • Quantitative 1: Simple TrigonometryQ1) If cosec 18°= sec A, then the measure of A is________a) 18° b) 108°c) 72° d) None of theseAns: c) 72°
  • SOLUTION Cosec 18° = Cosec (90° – 72°) As, Cosec (90 – Ѳ) = Sec Ѳ Cosec (90° – 72°) = Sec 72° Sec 72° = Sec A Hence, A = 72°
  • Quantitative 2 : Problem of AgesQ2) After 2 years, Paul will be 2 times as old as Alice. Presently he is 4 times as old. What is the present age of Paul?a) 1 year b) 4 yearsc) 2 years d) None of theseAns: b) 4 years
  • SOLUTIONLet present age of Paul be x yrs and that of Alice be y yrsAccording to condition no. 1 x + 2 = 2 (y + 2) x – 2y = 4 – 2 x – 2y = 2 -----(i)
  • According to condition no. 2 x = 4ySubstituting x in equation (i) 4y – 2y = 2 2y = 2 Hence, y = 1 years x= 4 years
  • Quantitative 3 : MensurationQ3) A vessel is in the form of a hollow cylinder mounted on a hollow hemisphere. The diameter of the hemisphere is 14 cms and the total height of the vessel is 30 cms . Find the outer surface area of the vessel. (take π = 22/7)a) 1628 cm² b) 1528 cm²c) 1474 cm² d) None of theseAns: c) 1474 cm²
  • SOLUTION d = 14 cm r = 7 cm Height of the cylinder = 30 – 7 = 23 cm Outer Surface Area of the Vessel = curved surface area of hemisphere+ curved surface area of cylinder + πr² (top surface) = 2 πr² + 2πrh + πr² = πr (2π + 2h + r) = 22/7 * 7 ( 2*7 +2*23 + 7) = 22 (14 + 46 + 7) = 22 * 67 = 1474 cm²
  • Quantitative 4 : Linear EquationQ4) A telephone company charges 80 paisa/ min for first 80 min of talk , 70 paisa/ min subsequently up to 130 min and 55 paisa/min beyond 130 min. What would be the amount paid by a subscriber who has used a total of 110 min of talk time?a) Rs. 85 b) Rs. 108.c) Rs. 64 d) None of theseAns: Rs. 85
  • SOLUTION Total Charges = (80 min x 80p) + (30 min x 70p) = 6400p + 2100p = 8500p = Rs. 85
  • Quantitative 5: Linear EquationQ5) (2/3rd) of a number is 4 more than (1/6th) of the same number. What is the number? a) 6 b)8 c)36 d)24Ans: b) 8
  • SOLUTION Let number be x Then 2/3x = 1/6x + 4 2/3x – 1/6x = 4 [(4-1)/6] x = 4 3x/6 = 4 x = 4x6/3 = 8
  • Quantitative 6 : ProbabilityQ6) Paul the octopus who has been forecasting theoutcome of FIFA world cup matches with tremendousaccuracy has now been invited to predict ICC world cupmatches in 2011. We will assume that the world cupcontenders have been divided into 2 groups of 9 teamseach. Each team in a group plays with the other teamsin the group. The top two teams from each group enterthe semi finals ( after which the winner is decided byknockout).However, Paul has a soft spot for India and when Indiaplays with any team, Paul always backs India. Alas, hispredictions on matches involving India are right only 2out of 3 times. In order to qualify for the semi finals, it issufficient for India to win 7 of its group matches. Whatis the probability that India will win the ICC world cup?
  • 6(b)a) (2/3)^10b) (2/3)^9 + 8/3 * (2/3)^9c) 1/3 * (2/3)^9d) (2/3)^10 + 8/3*(2/3)^9Ans: c) 1/3 * (2/3)^9
  • SOLUTION1. To win semifinals India needs to win 7 matches and can loose one.2. To win a match probability = 2/33. Probability of loosing a match = 1/34. To qualify for semifinals India needs to win 7 matches the probability of which is (2/3)⁷5. For India to reach the semifinals the probability is (2/3)⁷ x 1/3.6. Now, to further win semifinals and final both probability is 2/3 X 2/3.7. Therefore overall probability of India wining = (2/3) ⁷ x 1/3 x 2/3 x 2/3 = (2/3)⁹ x 1/3.
  • Note:I. If India wins all the matches i.e. 8+2=10 matches, probability = (2/3)102. The key is that for reaching semi finals India has to win only 7 matches out of 8 and can afford to loose one.
  • Quantitative 7 : ProbabilityQ7) A toy train produces 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 4c) 1 in 8 d) None of these
  • 7(b)Ans: a) 1 in 16
  • SOLUTION• A toy train produces 10 different tunes in the normal course• But now as the toy train has become defective, it produces only 2 different tunes; so the probability of producing any one tune is ½.• Probability of producing 4 consecutives same tunes = ½ x ½ x ½ x ½ = 1/16 or 1 in 16
  • Quantitative 8 : ProbabilityQ8) Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who gets to cut the cake first and have a piece of the cake. One friend suggests that they can make 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?
  • 8(b) a) 8 b) 10 c) 9 d) All are equally likelyAns: a) 8
  • SOLUTIONSum making up to number 8 in one set of throw of die and picking up the card, probable sets are = (2,6), (6,2), (4,4), (5,3), (3,5) = Total 5 setsSums making up to number 9, probable sets are = (4,5), (5,4), (6,3), (3,6) = Total 4 setsSums making up to number 10, probable sets are = (5,5), (6,4), (4,6) = Total 3 setsSo probability of 8 would be the maximum appearing more often than others
  • Quantitative 9 : ProbabilityQ9) A lady has fine gloves and hats in hercloset- 18 blue- 32 red and 25 yellow gloves arethere. The lights are out and it is totally dark .Inspite of the darkness she can make out thedifference between a hat and a glove. Shetakes out an item out of the closet only if she issure that it is a glove. How many gloves mustshe take out to make sure that she has a pair of each colour?a) 50 b) 8c) 59 d) 42
  • 9(b)Ans: c) 59
  • SOLUTIONWe have to consider the worst case scenario for being sure.Suppose 1st she takes out all 32 Red gloves (the maximum number possible for one colour)Then all yellow gloves which are 25 in numberAnd then next 2 gloves she takes out that will definitely be of blue colorIn this way to make sure that she has a pair of each color, she has to take out = 32 + 25 + 2 = 59 gloves.
  • Quantitative 10 : ProbabilityQ10) There are 7 children in a family and the youngest child is a boy. What is the probability that all of them are boys ? a) 1/2! b) 1/64 c) 1/128 d) 1/8Ans: b) 1/64
  • SOLUTION :The probability of a child being boy or girl is ½ (assuming it is random)The probability that all children in the family are boys when the youngest child is a boy = ½ x ½ x ½ x ½ x ½ x ½ x 1 = (1/2)^6 = 1/64
  • Quantitative 11 : Number SystemQ11) A number when divided by D leaves a remainder of 3 and when divided by 3D leaves a remainder of 21 . What is the remainder, when twice the number is divided by 3D?a) 15 b) 42c) 3 d) cannot be determinedAns: a) 15
  • • SOLUTION-1. As the remainder is 21 when divided by 3D Therefore, 3 D >21 or D>72. Let us take the next higher value i.e. D=8 & 3D = 24 (a). The first option is number 45 (=24+21) Divided by 24 it leaves a remainder of 21 Divided by 8 it leaves a remainder of 5 So it does not fulfill the conditions (b). Let us try the next possibility i.e. 45+24 = 69 Divided by 24 (3D) it leaves 21 as remainder But divided by D = 8, it leaves 7 as the remainder – so it does not fulfill the condition
  • 3. Let us make next trial with ‘D=9’ 3D = 27 (a). Let first number be 48 Divided by 3D = 27 it leaves 21 as remainder Divided by D=9 it leaves 3 as remainder So 9 is the desired number ‘D’ Let us now divide double the number i.e. 96 by 3D = 27 remainder is 15 So a= 15 is the correct answer
  • Quantitative 12 : Permutation and CombinationQ12) Alok is attending a workshop “How to do more with less” and todays theme is Working with fewer digits. The speakers discuss how a lot of miraculous mathematics can be achieved if mankind (as well as womankind) had only worked with fewer digits. The problem posed at the end of the workshop is How many four digit numbers can be formed using the digits 1, 2,3,4 ,5 ( but with repetition) that are divisible by 4? Can you help Alok find the answer?
  • 12 (B) a)100 b) 125 c) 75 d) 85Ans: b) 125
  • SOLUTIONA number to be divisible by 4 the last 2 digits should be divisible by 4To fill the last two digits that are divisible by 4 are (1,2), (2,4), (3,2), (4,4), (5,2)Therefore there are 5 possibilities.And the rest 2 digits can be filled in ⁵P₅ ways.So total there are 5*5*5 ways = 125 ways
  • Quantitative 13 : Permutation and CombinationQ13) A research lab in Chennai requires 100 mice and 75 sterilized cages for a certain set of laboratory experiments. To identify the mice, the lab has prepared labels with numbers 1 to 100 , by combining tags numbered 0 to 9. The SPCA requires that the tags be made of toxin-free material and that the temperature of the cages be maintained at 27 degree Celsius. Also , not more than 2 mice can be caged together and each cage must be at least 2 sq. ft in area. The 5 experiments to be conducted by lab are to be thoroughly documented and performed only after a round of approval by authorities. The approval procedure takes around 48 hours. How many times a tag having number 4 is used by the lab in numbering these mice?
  • 13(b) a) 9 b) 19 c) 20 d) 21Ans: b) 19
  • SOLUTION• Tag having number 4‘ are as follows• 4, 14, 24, 34, 44, 54, 64, 74, 84, 94• 40, 41, 42, 43, 45, 46, 47, 48, 49• So a total of 19 times.
  • Quantitative 14 : Permutation and combinationQ14) 20 people meet and shake hands. What is the maximum number of hand shakes possible if there is to be one ‘cycle’ of handshakes { a cycle of handshake is a sequence of people (a1,a2,…..ak) such that people (a1,a2),(a2,a3)…..(a(k-1),ak), (a20,a1) shake hand} a) 18 b) 19 c) 20 d) 21Ans: c) 20
  • SOLUTION 20 1 2 3 19 4 5 18 6 17 16 7 8 15 9 14 10 13 12 11 To make a complete cycle number of handshakes required is 20
  • Quantitative 15 : Time and DistanceQ15) On planet korba, a solar blast has melted the ice caps on its equator. 9 years after the ice melts, tiny planetoids called Echina start growing on the rocks. Echina grows in the form of a circle ,and the relationship between the diameter of this circle and the age of echina is given by the formula d = 4*√ (t-9) for t ≥ 9 where d represents the diameter in mm and t the number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur?
  • 15(b) a) 17 b) 21.25 c) 12.25 d) 12.06Ans: b) 21.25
  • SOLUTIONThe relationship between the diameters of the circle and the age of Echina is given by the formulaD = 4 x √(t – 9) for t>=9If radius r is 7 mm then diameter = 7 x 2 = 14 mm 14 = 4 x √(t – 9) 14/4 = √(t – 9) 7/2 = √(t – 9) squaring both sides 49/4 = (t – 9) So t = 21.25

  • Reading Comprehension-1Q45)The recent news, that local hospitals have had to reroute seriously illpatients because the communitys critical-care beds are full, is worrisome.Earlier this week, four of the six local hospitals ran out of space for thecritically ill and had to turn people away.Federal law requires hospitals to treat anyone who walks in. As a result ofhaving to treat large number of uninsured patients, the emergency roomsoften become an economic drain on their hospitals. Doctors now want to setup their own free-standing ambulatory surgical facilities and diagnosticcenters. Critics contend this would leave hospitals with less revenue and thesame number of indigents to treat. A bill was recently introduced to phaseout the need for a "certificate of public need" for non-hospital-basedfacilities, provided those facilities met stringent regulations andrequirements. This would have made it easier to set up alternative facilitiesto help indigent patients. The finance committee balked at the hefty priceand killed the bill, another casualty of a failed legislative session.Unfortunately, the problem of access to medical care for those of limitedmeans is not going to go away anytime soon and, despite the well-intendedregulations, full hospitals compromise everyones welfare. Healthycompetition with small neighborhood surgical and diagnostic centers may bewhat is necessary to help dampen rising medical costs. But under nocircumstances should the hospitals be forced to care for everybody withouthealth insurance while competitors operate free of the burden of caring forthose unable to pay.
