L&T INFOTECH PAPER ON 2ND NOVEMBER AT ABES GAZIABAD

I am SUNIL SHARMA of BHARAT INSTITUTE OF TECHNOLOGY MEERUT. I recently attended L&T infotech campus recruitment held at 2nd -4th NOVEMBER 2007 at ABES Gaziabad.

Guys it was my 7 th company n I was able to clear written test of only 3 company including lnt.. (TCS ,HUGHES Communication)I lost my all hope of getting good job but was having a belief in me n GOD n Kept on working 4 prepaeration of Companies.Finally I got news of selection on Diwali after 4 days of giving interview.

Eligibilities:

Should have consistently scored atleast 60% in 10th, intermediate and BTECH all sems. hould not have any history of fails in any class or semester. Process of Selection: 1) Written test on quantitative aptitude, reasoning and English each section consists of 30 questions => total 90 questions in 90 minutes. No negative marks 90 marks. There is sectional cutoff so u need to score in all sections properly The sectional cutoff was around 18-20 Note: there are 3 sets of papers almost same standard. 2) Technical interview followed by group discussion 3) HR interview

GROUP DISCUSSION

WELL we all were to sit together n have to speak strictly 2 minute on atopic of our choice n have to tell abt our intro,achievement n then topic in this mean time.Guys it sound easy but was?nt my 7 classmate were rejected in this most of them werw good speaker.

Technical Interview:

I gave my interview in very starting in morning. We were told to be ready 4 Tech. Interview but as I entered interview The guy started taking a H.R. Interview, n which ended as stress interview.In last He asked a C program on sorting n asked about sorting algorithm.

H.R. INTERVIEW

HE Spoke only in Hindi through out interview.In starting He said to ask any 3 question which will decide my selection but said he?s not gonna to answer them. Then asked what I know about lnt n asked some terms like Operation ,maintenance, A major racent happening of IT Industry. I told so many event but he was n?t satisfied.

Asked Why I din?t cleared aptitude test in previous attempt. I answered but He said This time it?s a fluke nothing else ,I tried to to make him understand that it?s not a fluke but this all was in vain.

Asked about Achievements in detailed n puled my leg as much he can.

Guys when I came out of interview room ,I was just about to weep. I was having only belief in God 4 a miracle n that happened

I got the news of selection on eve of DIWALI .Thank God Really guys it?s a like a miracle.

Questions in Written Test:

Aptitude:

Same questions come every time so better prepare these questions n go with confidence.

1. In a kilometer race between A and B, A beats B by 9 seconds or 36 meter. Then what is the time taken by B to finish the race. Sol: When A has just completed the race it means B is behind by 36mts or completed 966mts. And when a has taken T seconds to complete the race B needs another 9 secs to complete the race; that means B runs another 36mts in 4sec so his speed is 36/9 = 4mts/sec. So travels 1000mts or 1km in 1000/(36/9)=250secs(time=dist/speed). So A completes race in 250-9sec=241secs [refer rs aggarwal quant aptitude race and gameof skills eg problem ] 2. If 4apples and 6oranges cost 13/- and 2apples & 4oranges cost 7/- find cost of one apple and one orange. Sol: subtract 2nd eqn from 1st then we have 2a-2o=6 =>1apple and 1orange cost 3/-

3. If a person travels for P km in t hrs and then increases his speed by x km/hr find his new speed. a) (p/t)+x b) pt+x c)p/x+t d)pt/x ans:a 4,5,6 questons based on statistics from a bar graph 7. If a kite is at a height of 50mts from ground and the angle of inclination from a point on ground is 60degree then find length of the kite sting. Sol: based on trigonometry heights and distances: sin60=height of kite/length of string(altitude/hypotenuse) ans:100/(root of 3)

8. If avg. of 6 nos. is 8 and later 2 new nos. are added such that the avg of the present 8 nos is 6 then what is the avg of newly added two nos.

Sol: avg=total sum of values/ no of objects or observation 8 =total sum of values of 6 nos /6 total sum of values of 6 nos=6*8=48 now when 2 new nos are added applying same formula 6= total sum of values of 8 nos/8 total sum of values of 8 nos=48 so the value has not changed which means the sum of added 2 nos is zero soavg=zero/2=zero (ans) 9.What % of 4/7 is 4/5? Sol: {(4/5)/(4/7)}*100= ans =140% 10. By what % should a person sell an article so as to gain a profit of 24% even after giving a discount of 10 %

Sol) the easiest way to solve such problems is by assuming the cost price as 100rs So to get a profit of 24% means to sell at 100+24=124/- So suppose he sold it at 10% discount initially he sells at 90rs so ther is a difference of 34/- 11.One problem on Arithematic progression

12.One on mean

13. Matrix addition: If 1 2 3 1 1 1 0 1 2 5 7 9 = 3 4 7 + 2 3 2 2 3 4 1 1 1 1 2 ? then what is the value of ? ans: 4-1=3 14. Find the determinant of a 3*3 matrix? very easy

15. A red light glows every 10sec, yellow every 15sec and red every 18sec. find the number of times all three glow together from 8:00AM to 9:00AM (including both times)

Sol :LCM of 10,15,18 = 90. So every 90 seconds all three glow together so in one hour there are 3600 secs. So 3600/90=40 times but answer is 41 because they glow at 0th second that is at 8 Am since both times are included.

16. If a man travels at 30km/hr is behind a car by 40mtrs. In 20sec if he leads the car by 20mts then what is speed of car

17. If age of a person is x and his mothers age is 34. then after how many years will the mothers age be twice of the son? (don't worry ans will be given in terms of x and we can answer it)

18. One more age problem

19. If a person takes 5 days and 8 hrs to dig a trench ; then how many persons will dig 3 trenches in 1 day (with each day of 8 hrs work)

20,21,22 questions based on arthematic calculation to check ur speed in calculating.(they may be time consuming though easy unless u can do some short cuts so better to avoid)

One q based on allegation and mixture go for error and trial method. Not able to recollect other 7 questions

Verbal test: 30 questions

Meanings 3 questions:

Faux Pas : means a blunder (spelled as fau pa) Don't remember other two Arranging sentences in order(3 or 4 questions) Finding errors in a sentence(3 Qs) Reading passage (5 questions ): easy to score atleast 4 marks out of 5 by reading questions and coming to passage to search answer also less time consuming Also anologies

Reasoning

Based on venn diagram 3 questions

1) Which diagram best represents musician, violinist and instrumentalist

Ans: three concentric circles the outermost circle being musician the inner circle instrumentalist and the innermost being violinist. Because every violinist a musician

and instrumentalist but not the viceversa. Every instrumentalist is a musician but not the viceversa

2) polygon, quadrilateral and rhombus Ans : the same as above answer rhombus is the innermost then the quadrilateral and outside is the polygon Explanation: a polygon is a 3 or more close sided figure so even a triangle and pentagon are polygons so is a quadrilateral which is a 4 sided fig and quad includes rombus, square, rectangle, kite, trapezium etc

Not able to remember other one

Three questions on seating arrangement (easy) 3 questions based on giving 3 figures and then we are required to find the 4th fig which comes next in the logical sequence (easy)

Sol: subtract 2nd eqn from 1st then we have 2a-2o=6 =>1apple and 1orange cost 3/-

a) (p/t)+x b) pt+x c)p/x+t d)pt/x ans:a

4,5,6 questons based on statistics from a bar graph

7. If a kite is at a height of 50mts from ground and the angle of inclination from a point on ground is 60degree then find length of the kite sting.

Sol: based on trigonometry heights and distances: sin60=height of kite/length of string(altitude/hypotenuse) ans:100/(root of 3)

Sol: avg=total sum of values/ no of objects or observation

8 =total sum of values of 6 nos /6

total sum of values of 6 nos=6*8=48

now when 2 new nos are added applying same formula 6= total

sum of values of 8 nos/8

total sum of values of 8 nos=48 so the value has not changed which means the sum of added 2 nos is zero soavg=zero/2=zero (ans)

9.What % of 4/7 is 4/5?

Sol: {(4/5)/(4/7)}*100= ans =140%

10. By what % should a person sell an article so as to gain a profit of 24% even after giving a discount of 10 %

11.One problem on Arithematic progression

If 1 2 3 1 1 1 0 1 2

5 7 9 = 3 4 7 + 2 3 2

2 3 4 1 1 1 1 2 ?

then what is the value of ? ans: 4-1=3

14. Find the determinant of a 3*3 matrix? very easy
