Robert Bosch Placement Paper July 2010

Robert Bosch Paper on 31st July 2010 At Vardhaman Engineering College, Shamshabad

Question paper pattern: (COMPUTER SCIENCE)
Each question carries 2 marks and -.5 negative for wrong answers.
.
NOTE: The same question paper would be coming for the cse and it students….Better to have a glance of this paper before u take the written exam…
The Question paper consists of three Sections
a) Technical(1-35)
-Mainly on C, Operating Systems, Computer Networks, Data Structures,

b) Quantitative(36-50)
– Mainly on A.P, G.P , General Maths, Profit and Loss, Ratios(etc..)
c) English(51-60)
– (51-52)inferring from passages,,(53-55)..Logical Deductions.. (56-57)..Sentence Correction (58-60) ..Arrangement of jumbled sentences.
a) Technical:

1)#include.
main()
{
int const *p = 10;
printf(?%d?, ++(*p));
}
Ans: Compilation Error
sol: Constant cant be modified.
2) .main()
{
int I;
char *a = ?man?;
for(i=0;i<3;i++)
printf(?%c%c%c%c\n?,i[a],a[i],*(a+i),*(i+a));
}
ans: mmmm
aaaa
nnnn

3)main()
{
extern int i = 10;
printf(?%d?,i);
}
Ans: Compiler error

4)main()
{
float f= 1.1;
double d = 1.1;
if ( f == d)
printf(?I LOVE U?);
else
printf(?I HATE U?);
}
Ans: I HATE U
Sol: Due to precision Considerations …
5) A tree was given and postorder traversal is to be found out…(Easy)

6) What is the name of the Command used to partition the disk
ANS: fdisk
Sol: When you run the fdisk and format commands, the Master Boot Record (MBR) and file allocation tables are created. The MBR and file allocation tables store the necessary disk geometry that allows hard disk to accept, store, and retrieve data

7)A question from MS-DOS
ans)msconfig.exe

CoolA quesion is on paging(Memory management)
Formulae: Effective access time=((1-p)*m+(p*s))
where (1-p) is called hit ratio, p is called page fault ratio, ‘m’ is called main memory access time, ‘s’ is called pagefault service time.

9) The header file that is included to use manipulators is
sol:

10) Which data structure is easier to implement the trees…???
sol: Linked Lists..

11)Function used to display the character on the console is ..??
sol: PUT

12) No of nodes in a perfect Binary tree is..??
sol: (2*n-1)

13) No of queues needed to implement the priority queue..??
ans:two
sol: Priority queue uses two queues
1) for storing the data
2) other for storing the priorities.

14)Heterogeneous Linked List is implemented using…???
sol: void pointers

15) a variable used to store the address of another variable is termed as..??
sol: Pointer..

16) #include
void main()
{
int i = 15;
int const &j = i;
cout << i << j << endl;
i = 9;
cout << i << j << endl
}
ANS:
15 15
9 9

17)Virtual Memory consist of main memory and …???
sol: Swap files

1Cool Which class addressing system has less no of hosts…???
sol: class D(not sure)

19)Which of the following is a network layer protocol
a) TELNET b) FTP. c)smtp d)none
sol: telnet

20)many questions on computer networks….( around 10 questions….i left all of them)

Prepare ‘top down approach’ – ross and kurose for computer networks…it would be helpful..

b) Quantitative:
36) a man sells an article with a 20% discount and gain a profit of 20%…what would be the profit percentage if he sells it with 10% discount…??
sol; 35(not sure)

37)sum of the infinite terms in a gp is 230 and sum of squares is 23 …find the common ratio.
sol: 10/13

3Cool fourth term of an ap is 200 and first term is 5 find the tenth term…??
ans:

39) if S+2R=220 and S=80 then R=.???
sol: 70

40) if 25% of x=y then 67.5% of x in terms of y is…
sol: 100/y2 (not sure)

41)A student was performing an arithmetic operation and he multiplied a number by 3/2 instead of dividing it by 2/3 …what was its error percentage..??
sol: 0%

42) Probability:
a radioactive element disintegrates by 20 th part every hour and find the probability that no matter is left out in a duration of 45 min…??
sol: since it deals with radioactive element ‘n’ is usually large..so poissons distribution is to be applied…
1hr=60min———-20
45min———-?
(45*20)/(60)=15..
Hence lamba=15

P(x=0)= (e-15)*(150)/(0!)
=(e-15)

43) If side of the square is x+2 and side of equilateral triangle is 2x and the perimeters of both square and equilateral triangle are equal …then find the value of x..??
sol: 4*(x+2)=(3*2x)
i.e; x=4

44) if side of the square of increased by 5 and change in area was 165 then find the value of side of the square…??
sol: (x+5)2-x2=165
10x+25=165
10x=140
x=14

45 -50)) similar questions were given and were easy….

c)English
51-52) a passage with inferences to be drawn…

53) saritha and kavitha are seperated by a certain distance of 100m and walking towards each other and savitha started from her house and walked for 30m East and turned right and walked upto 10m and then turned left and walked upto 20m and again turned left and walked to the road …what is the distance between the two girls now..??
sol: i think 20m(not sure jus try..)

54 and 55) deductions

56) choose which part has error A or B or C or D
we entered(A)/into the room(B)/after the class was over(c)/No Error(D)
sol: we entered the room after the class was over
ans: B

57) we discussed(A)/about the pollitics(B)/ in the class room(C)/No Error(D)
sol: we discussed the pollitics in the class room.
ans: B

58-60) arrangement of sentences and are very easy…. jus follow the sequence of time and situtation….
