B. Statement (2) ALONE is sufficient, but statement (1) is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient
Ans. D
Explanation:
For (1), the fact that a positive number multiplied by b has a positive product Establishes that b is a positive number. For (2), any positive number with a negative sign placed in front of it will become negative, indicating that b is a positive number

A. 25
B. 30
C. 40
D. 20
Ans. B
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 days
Question 16

void main()
{
int const * p=5;
printf("%d",++(*p));
}
A. compiler error
B. 6
C. 5
D. 7
Ans. A
Explanation:
Compiler error: Cannot modify a constant value. Explanation: a pointer to a "constant integer". But we tried to change the value of the " constant integer".
Question 17

{
int i=10;
i=!i>14;
Printf ("i=%d",i);
}
A. 10
B. 0
C. 14
D. 13
Ans. B
Explanation:
In the expression !i>14 , NOT (!) operator has more precedence than ' >' symbol. ! is a unary logical operator. !i (!10) is 0 (not of true is false). 0>14 is false (zero).

C. 0,1,2
D. BLUE,GREEN
Ans. C
Explanation:
enum assigns numbers starting from 0, if not explicitly defined.
Question 19
A man was engaged on a job for 30 days on the condition that he would get a wage of Rs. 10 for the day he works, but he have to pay a fine of Rs. 2 for each day of his absence. If he gets Rs. 216 at the end, he was absent for work for ... days
A. 6
B. 12
C. 7
D. 21
Ans. C
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 = 30-23 =7 days

Question 21
If a light flashes every 6 seconds, how many times will it flash in ¾ of an hour?
A. 450
B. 451
C. 350
D. 425
Ans. B
Explanation:
There are 60 minutes in an hour. In ¾ of an hour there are (60 * ¾) minutes = 45 minutes. In ¾ of an hour there are (60 * 45) seconds = 2700 seconds. Light flashed for every 6 seconds. In 2700 seconds 2700/6 = 450 times. The count start after the first flash, the light will flashes 451 times in ¾ of an hour.

A. 20
B. 30
C. 40
D. 50
Ans. B
Explanation:
suppose total income is 100 y is 70 z =60 total=210 but total money is 300 300-210=90 so they are getting 90 rs less 90 is 30% of 300 so they r getting 30% discount

A. 0
B. 1
C. -1
D. -2
Ans. C
Explanation:
bcoz g(2)=g(1)-g(0)=1+1=2 g(3)=1 g(4)=-1 g(5)=-2 g(6)=-1
Question 27
If A can copy 50 pages in 10 hours and A and B together can copy 70 pages in 10 hours, how much time does B takes to copy 26 pages?
A. 4
B. 3
C. 5
D. 1
Ans. B
Explanation:
A can copy 50 pages in 10 hrs. A can copy 5 pages in 1hr.(50/10) now A & B can copy 70 pages in 10hrs. thus, B can copy 90 pages in 10 hrs.[eqn. is (50+x)/2=70, where x--> no. of pages B can copy in 10 hrs.] so, B can copy 9 pages in 1hr. therefore, to copy 26 pages B will need almost 3hrs. since in 3hrs B can copy 27 pages.
Question 28
what's the answer for that :
A, B and C are 8 bit no's. They are as follows:
A -> 1 1 0 0 0 1 0 1
B -> 0 0 1 1 0 0 1 1
C -> 0 0 1 1 1 0 1 0 ( - =minus, u=union)
Find ((A - C) u B) =?
A. 10111011
B. 10111110
C. 10011110
D. 10001111
Ans. A
Explanation:
To find A-C, We will find 2's compliment of C and them add it with A, That will give us (A-C) 2's compliment of C=1's compliment of C+1 =11000101+1=11000110 A-C=11000101+11000110 =10001001 Now (A-C) U B is .OR. logic operation on (A-C) and B 10001001 .OR . 00110011 The answer is = 10111011, Whose decimal equivalent is 187.
Question 29
One circular array is given(means memory allocation takes place in circular fashion) diamension(9X7) and sarting address. is 3000, What is the address of (2,3)........
A. 3112
B. 3012
C. 3102
D. 3120
Ans. B
Explanation:
it's a 9x7 int array so it reqiure a 126 bytes for storing.b'ze integer value need 2 byes of memory allocation. and starting add is 3000 so starting add of 2x3 will be 3012
Question 30
In a two-dimensional array, X (9, 7), with each element occupying 4 bytes of memory, with the address of the first element X (1, 1) is 3000, find the address of X (8, 5).
A. 3212
B. 3122
C. 3211
D. 3210
Ans. A
Explanation:
initial x (1,1) = 3000 u hav to find from x(8,1)so u have x(1,1),x(1,2) ... x(7,7) = so u have totally 7 * 7 = 49 elementsu need to find for x(8,5) ? here we have 5 elements each element have 4 bytes : (49 + 5 -1) * 4 = 212 -----( -1 is to deduct the 1 element ) 3000 + 212 = 3212
