    2. FILL THE BLANKS:

    Observe the dilemma of the fungus; it is a plant, but possesses no chlorophyll. While all other plants put the sun’s energy to work for them combining the nutrients of ground and air into the body structure._____1______.Chlorophyll is found in these other plants which, having received their energy free from the sun, relinquish it__2__.



    In this search of energy, the fungus has become the earth’s major source of rot and decay. Wherever you see mould forming on a piece of bread, or a pile of leaves turning to compost, or a bloom down tree becoming pulp on the ground, _____3___.

    With fungus action, the earth would be pooled high with_____4______.



    In fact, certain plants which contain resins that are ____5_______. Specimen of the redwood tree, for instance can still be found ______6________.

    You are watching a fungus acting
    Resting on the forest floor centuries after having been cut down
    Responsible for decomposition of much plant life
    Fungus must look elsewhere for an energy supply
    Cannot produce their own store of energy
    The dead plant life of past centuries
    At some point in their cycle either to animal or to fungi
    Fungus is vastly different from other plants
    Toxic to fungi will last indefinitely.

    One large passage-6marks.
    I answer all question from passage in guess becos i have no time to read whole passage care fully.

    QUANTITATIVE: 38 Q-40 M
    ALL CAME FROM PREVIOUS YR QUESTION. U SHOULD KEEP ON UR MEMORY THE ANSWER OF EACH QUESTION .
    THERE IS 3 Q FROM VENN DIAGRAM & 3 FROM PIE CHART.


    1. Two pencils costs 8 cents, then 5 pencils cost how much
    Sol: 2 pencils è 8 cents => 1 pencil è 4 cents
    Therefore 5 pencils cost = 5 * 4 = 20 cents

    2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
    Sol: (A+B) can do the work in = 1/24 min.
    A alone can do the same work in = 1/40 min.
    B alone can do the same work in = (A+B)’s – A’s = 1/24 – 1/40 = 1/60
    Therefore, b can do the same work in = 60 min

    3.A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
    Sol Before the trip, car is filled with = 4 ½ gallon of oil
    Let ‘X’ be the quantity of fuel consumed for the trip in one direction
    The fuel consumed while going = X + ¼
    The fuel consumed while coming = X
    Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½
    ð 2X + ¼ = 4 ½ => 2X = 4 ½ - ¼ => 2X = 4 ¼ => X= 2. approx
    Therefore the fuel consumed while coming = 2 gallon

    4. Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?
    Sol: 40 deg.

    6. A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
    Sol: Let ‘x’ be the speed limit
    Person ‘A’ was fined for exceeding the speed limit by = 10mph
    Person ‘B’ was fined for exceeding the speed limit by = twice of ‘A’
    = 2*10mph=20mph given that the second person was traveling at the speed of 35mph => 35mph – 20mph = 15mph
    Therefore the speed limit is =15 mph

    7.A bus started from bus stand at 8.00am, and after 30 minutes staying at destination, it returned back to the bus stand. The destination is 27 miles from the bus stand. The speed of the bus is 18mph. In return journey bus travels with 50% fast speed. At what time it returns to the bus stand?

    11.) 6 persons standing in queue with different age group, after two years their average age will be 43 and seventh person joined with them. hence the current average age has become 45. find the age of seventh person?

    Solution: Here the question appear as an easy one, but carried a lot of unwanted sentences and unwanted datas(i dint mention above) in exam which may confuse u on solving technique.

    Let x be current average age of first 6 persons in queue and current age of seventh person be y. Then 6x will become the sum of those 6 persons age.

    Now, let compute the sum of those 6 persons after two years, 6x+12 (as each and individual increase their age by 2). hence its average become (6x+12)/6 = 43 (give in question itself).

    So now we can compute x from above equation. (x = 41, 6x = 246)

    Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y.

    Ans: 69


    12) Horse started to chase dog as it relieved stable two hrs ago. And horse started to ran with average speed 22km/hr, horse crossed 10 mts road and two small pounds with depth 3m, and it crossed two small street with 200 mts length. After traveling 6 hrs, 2hrs after sunset it got dog. compute the speed of dog?

    Ans: As we have speed and travel time of horse, we can get distance travelled by it...

    Hence d = 22*6 = 132km,

    Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier).

    Hence speed of dog = 132/8 = 16.5km/hr

    Ans:16.5km/hr.

    TCS Paper on 29th August 2010 @ SRMCEM, Lucknow

    Question 1: There is a toy train that can make 10 musical sounds. It makes 2 musical sounds after being defective. What is the probability that same musical sound would be produced 5 times consecutively? ( 1 of _____) ?
    Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32
    32 will be the answer.
    (My friends got similar question with "3 times consecutively"; for that the answer would be 8)

    Question 2: Peter and Paul are two friends. The sum of their ages is 35 years. Peter is twice as old as Paul was when Peter was as old as Paul is now. What is the present age of Peter?
    Luckily, I had this question twice. Initially I left it because of the confusing statement but when I got the same question second time with different names of the friends (Pooja and Prasad) then I gave a little extra time and solved it.
    Answer: 20 years. I simply substituted the answers in the statement to find the best fit, because the statement in the question was pretty confusing.

    Question 3: The ages of two friends is in the ratio 5:6. After how many years will the ages be in the ratio 7:8?
    Answer: 10 years.

    Question 4: (There was a long story, I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that's not needed for the question.) All of the following combinations are possible to make a perfume EXCEPT:
    1) Balsalmic and Lilac
    2) Woody and Lemon
    3) Mimosaic and Woody
    4) Mimosaic and Lilac
    Answer: Mimosaic and Lilac. I have made the question here really easy to understand. But the actual question was in a twisted language and it was difficult to find the answer. It took me some time to get to the answer.

    Question 5: A girl has to make pizza with different toppings. There are 8 different toppings. In how many ways can she make pizzas with 2 different toppings.
    Answer: 8 * 7 = 56

    Question 6: A triangle is made from a rope. The sides of the triangle are A cm, B cm and C cm. (I do not remember the numerical value). What will be the area of the square made from the same rope?

    Question 7: What is the distance of the z-intercept from the x-intercept in the equation ax+by+cz+d=0. (I do not remember the values of a,b,c,d)

    Question 8: An athlete decides to run the same distance in 1/4th less time that she usually took. By how much percent will she have to increase her average speed?
    Answer: 33.33%

    Question 9: A horse chases a pony 3 hours after the pony runs. Horse takes 4 hours to reach the pony. If the average speed of the horse is 35 kmph, what s the average speed of the pony? (This question was really long with loads of irrelevant statement)

    These are a few questions that I could recall. I made through the aptitude round by attempting 16 questions. Next was Technical Interview Round.

    Technical Interview:
    Here I will discuss the technical questions that were asked to me and also the questions asked to my friends.

    Question 16: Why is the VIRTUAL keyword used in C++?

    Question 17: Which keyword is written to use a variable declared in one class in the other class?

    Question 18: Suppose a code is written in C and you want to use that code in C++. How can you do that?

    Question 19 What do you mean by DML?

    Question 20: Is there any language other than SQL where DML is used? If yes, then which?

    Question 21: How many normal forms do we have?

    Question 22: Here is a tic-tac-toe game which is being played by 2 people:
    x o _
    o _ _
    x o x

    _ represent the blank spaces. Who played the last chance (x or o)?

    Technical Questions asked to my friends:

    Question 1: What is a transaction? Properties of Transaction?

    Question 2: What "condition" will be written in the if statement such that both Hello World are printed when the following code is executed.

    if(condition)
    {
    printf("Hello");
    }
    else
    {
    printf("World");
    }

    Question 3: What will be the output of the following code?
    int i=5;
    printf("%d, %d, %d", i++, i, ++i);

    Which C compiler do you use? (My friend said TURBO)
    What will be the output of above code in TURBO compiler? (He said SAME)
    No! It will not be the same.

    After the technical round, there was an MR i.e. Managerial Round.
    It was just a 2-3 minutes round. The interviewer asked me to introduce myself. Then asked about my father. Then core values and strengths. Your hobbies? Which latest novel have you read?

    Tips to crack the written:

    1. Read the question from last 2 lines if not able to get go to last 3 lines bottom up approach is more importatnt because saying about (Eg: lilavathi ka hei8 he will ask product of 2 number what are those sum of squares of the same numbers at last) this why read it from last

    2. Topics to be concentrated in R.S Aggarwal uncle's book
    a) Pipes and cisterns (Only concentrate on methods like simulaneus filling taps and sequentital filling time taken and size of tub )2 problems
    b) Time and Distance (Average distance problems formula-2xy/(x+y) x-first speed y-second speed -1 prob and d=s*t simple problem only 1 so total 2 problems
    c)Numerical calculations simple problem based on (A+B)^2=A^2+B^2+2AB AND (A+B)^3


    But not directly he will ask it using lilavathi story telling the concept at last saying that product of two numbers is something and sum of two numbers is something find sum of squres of that number A+B is given AB is given solve it using A+B whole square formal and get sum of squares 2 problems
    d) Ages problems 2 problems
    e) Surface area and formulas on geomentry 1 problem
    f) Permutation -2 problems
    g) Probability -2 problems
    h) Blood relations -2 problems same problems from R.S uncle(Aggarwal)


    Just know the concept to solve and use the 1st tip its enough you will be able to solve 16 questions 3 puzzles are there which i will be sharing all the types.


    a) Uncle puzzle is there which means 7 rupees must be divided between 3 things banan, choco, biscuit for buying this for this type of puzzle answer is always 1. 1st item 2-2nd item1-3rd item squence is 1,2,1


    b) My papers as different puzzle that is 20 cake pieces must be divided among 3 people mother father and sons that is mother eats 2 pieces father eats 3 and son eats half so what will be the quantity to so choose the option which suits the question cum from options that is add the qunatity by father and mother and son to get total 20 which will suit it that is the answer.

    c) A question on arrangement on letters answers may me one is bird or animal if its repeteka its bird if its rigte its animal (tiger).


    d) A question on hand shake which is from shakus puzzle buk formula is 2^n=n(n-1)/2 number of hand shakes problem 8 people attending party number of hanshakes with cycle means 8*7/2=28 or if u find the word no cycle than answer is 7 one less

    e) A question on socks to be picked in dark room to get the socks of same color its number of choices total number of types of socks +1


    f) A problem on cake preparing toppings its always (ans:ncm=28) same as handshakes


    g) A problem on buliding number number of 2's or 3's or 4's etc upto 9 answer is always 20 (count 2 in 22 two times every body in this forms will written8 19 its worng its answer is 20 for 2-9 number and 21 for number of 1's because 100 is included.


    h) A problem on ohm law V=IR formula simple bit this problems if you prepare its enough to get 30 out of 35 may be 35 also but remaining 3 i don't know how to solve
