3. Here is the structure declaration of a doubly linked list
struct dlink
{
int nodeid;
struct dlink *next;
struct dlink *prev;
} dlink_t;
A pointer of the head of the linked list is maintained as a global variable, whose definition is
dlink_t *head; The funt remove_element(dlink_t *rp), needs to remove the node pointed to the
rp and adjust the head. The first node's prev and the last node's next are NULL.
remove_element(dlink_t *rp)
{
rp->prev->next = rp->next;
rp->next->prev = rp->prev;
if( head == rp)
head = rp->next;
} Which of the following statement is true about the fution remove_element

SECTION –II (C language Basics and programming) this section consists of 20 Questions…….. All
are programs only…
1. main()
{
printf("%x",-1<<4);
}
a) fff0
b) fffb
c) ff0
d) none
Ans: a
Explanation:
-1 is internally represented as all 1's. When left shifted four times the least significant 4 bits are filled
with 0's.The %x format
specifier specifies that the integer value be printed as a hexadecimal value.
2. main()
{
char *p;
p="Hello";
printf("%c\n",*&*p);
}
a) e
b) H
c) some address
d) ome garbage value
Ans: b
Explanation:
* is a dereference operator & is a reference operator. They can be applied any number of times
provided it is meaningful. Here
p points to the first character in the string "Hello". *p dereferences it and so its value is H. Again &
references it to an address and * dereferences it to the value H.
3. void main()
{
int i=5;
printf("%d",i++ + ++i);
}
a) 11
b) 12
c) 10
d) output cant be predicted
Ans: d
Explanation: Side effects are involved in the evaluation of i
4. main( )
{
int a[2][3][2] = {{{2,4},{7,8},{3,4}},{{2,2},{2,3},{3,4}}};
printf(“%u %u %u %d \n”,a+1,*a+1,**a+1,***a+1);
}
a) 100, 100, 100, 2
b) 101,101,101,2
c) 114,104,102,3
d) none
Ans: c
Explanation:The given array is a 3-D one. It can also be viewed as a 1-D array.
2 4 7 8 3 4 2 2 2 3 3 4
100 102 104 106 108 110 112 114 116 118 120 122
thus, for the first printf statement a, *a, **a give address of first element . since the indirection ***a
gives the value. Hence, the first line of the output.for the second printf a+1 increases in the third
dimension thus points to value at 114, *a+1 increments in second dimension thus points to 104, **a +1
increments the first dimension thus points to 102 and ***a+1 first gets the value at first location and
then increments it by 1. Hence, the output is C is correct answer…

Answers:
1. Answer:
30 days.
Explanation:
Before:
One day work = 1 / 20
One man’s one day work = 1 / ( 20 * 75)
Now:
No. Of workers = 50
One day work = 50 * 1 / ( 20 * 75)
The total no. of days required to complete the work = (75 * 20) / 50 =
30
2. Answer:

3. Answer:
5.3 %
Explanation:

4. Answer:
250 lines of codes
5
5. Answer:
7 days
Explanation:
The equation portraying the given problem is:
10 * x – 2 * (30 – x) = 216 where x is the number of working days.
Solving this we get x = 23
Number of days he was absent was 7 (30-23) days.
6. Answer:
150 men.
Explanation:
One day’s work = 2 / (7 * 90)
One hour’s work = 2 / (7 * 90 * 8)
One man’s work = 2 / (7 * 90 * 8 * 75)
The remaining work (5/7) has to be completed within 60 days, because
the total number of days allotted for the project is 150 days.
So we get the equation
(2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7 where x is the number of
men working after the 90th day.
We get x = 225
Since we have 75 men already, it is enough to add only 150 men.
7. Answer:
(c) 1
Explanation:
a percent of b : (a/100) * b
b percent of a : (b/100) * a
a percent of b divided by b percent of a : ((a / 100 )*b) / (b/100) * a ))
= 1
8. Answer:Cost price of horse = Rs. 400 & the cost price of cart = 200.
Explanation:-
Let x be the cost price of the horse and y be the cost price of the cart.
In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the
gain.
Therefore (10/100) * x = (20/100) * y
X = 2 * y -----------------(1)
6
In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by
Rs. 10.
Therefore (5 / 100) * x = (5 / 100) * y + 10 -------(2)
Substituting (1) in (2) we get
(10 / 100) * y = (5 / 100) * y + 10
(5 / 100) * y = 10
y = 200
From (1) 2 * 200 = x = 400

1,2,3 & 4
12. Answer:
B
13. Answer:
11 & 9 apples per tree.
Explanation:
Let a, b, c, d & e be the total number of apples bored per year in A, B,
C, D & E ‘s orchard. Given that a + 1 = b + 3 = c – 1 = d + 3 = e – 6
But the question is to find the number of apples bored per tree in C and D ‘s
orchard. If is enough to consider c – 1 = d + 3.
Since the number of trees in C’s orchard is 11 and that of D’s orchard
is 13. Let x and y be the number of apples bored per tree in C & d ‘s orchard
respectively.
Therefore 11 x – 1 = 13 y + 3
By trial and error method, we get the value for x and y as 11 and 9

Since Hopper writes Gothic romance and Heron publishes the novel
spy thriller, Blueja publishes the novel by Hopper.
Since Heron publishes the novel spy thriller and Heron publishes the
novel by Gorky, Gorky writes Spy thriller and Rathko writes Murder mystery.

30. Answer:
x = 4
Explanation:
Since the side of the square is x + 2, its perimeter = 4 (x + 2) = 4x + 8
Since the side of the equilateral triangle is 2x, its perimeter = 3 * 2x = 6x
Also, the perimeters of both are equal.
(i.e.) 4x + 8 = 6x
(i.e.) 2x = 8  x = 4.
31. Answer:
5 (y – 2) / y.
Explanation:
To type a manuscript karthik took y hours.
Therefore his speed in typing = 1/y.
He was called away after 2 hours of typing.
Therefore the work completed = 1/y * 2.
Therefore the remaining work to be completed = 1 – 2/y.
(i.e.) work to be completed = (y-2)/y

35. Answer:
Cost price of horse: Rs. 400 &
Cost price of cart: Rs. 200
Explanation:
Let x be the cost of horse & y be the cost of the cart.
10 % of loss in selling horse = 20 % of gain in selling the cart
Therefore (10 / 100) * x = (20 * 100) * y
 x = 2y -----------(1)
5 % of loss in selling the horse is 10 more than the 5 % gain in selling
the cart.
Therefore (5 / 100) * x - 10 = (5 / 100) * y
 5x - 1000 = 5y
Substituting (1)
10y - 1000 = 5y
5y = 1000
y = 200
x = 400 from (1)

2. A fast typist can type some matter in 2 hours and a slow typist can type the same in
3 hours. If both type combinely, in how much time will they finish?
Answer : 1 hr 12 min
Explanation : The fast typist's work done in 1 hr = 1/2
The slow typist's work done in 1 hr = 1/3
If they work combinely, work done in 1 hr = 1/2+1/3 = 5/6
So, the work will be completed in 6/5 hours. i.e., 1+1/5 hours = 1hr 12 min
3. Gavaskar's average in his first 50 innings was 50. After the 51st innings, his
average was 51. How many runs did he score in his 51st innings. (supposing that he
lost his wicket in his 51st innings)
Answer : 101
Explanation : Total score after 50 innings = 50*50 = 2500
Total score after 51 innings = 51*51 = 2601
So, runs made in the 51st innings = 2601-2500 = 101
If he had not lost his wicket in his 51st innings, he would have scored
an unbeaten 50 in his 51st innings.

Explanation : The number closest to 100 which is greater than 100 and
divisible by 14 is 112, which is the first term of the series which has to be summed.
The number closest to 1000 which is less than 1000 and divisible by 14
is 994, which is the last term of the series.
112 + 126 + .... + 994 = 14(8+9+ ... + 71) = 35392
8. If s(a) denotes square root of a, find the value of s(12+s(12+s(12+ ...... upto
infinity.
Answer : 4
Explanation : Let x = s(12+s(12+s(12+.....
We can write x = s(12+x). i.e., x^2 = 12 + x. Solving this quadratic equation,
we get x = -3 or x=4. Sum cannot be -ve and hence sum = 4.
9. A cylindrical container has a radius of eight inches with a height of three inches.
Compute how many inches should be added to either the radius or height to give the
same increase in volume?
Answer : 16/3 inches
Explanation : Let x be the amount of increase. The volume will increase by
the same amount if the radius increased or the height is increased.
So, the effect on increasing height is equal to the effect on increasing the
radius.
i.e., (22/7)*8*8*(3+x) = (22/7)*(8+x)*(8+x)*3
