Quantitative Aptitude [ Question No: 1 To 2 ] :
A number is increased by 10% and then decrease by 10%. Find the net decrease percent.
Your Answer : (Not Answered)
Correct Answer : B
The net decrease is 1%.
Take the number as 100. After a 10% increase it becomes 110; a 10% decrease of 110 removes 11, leaving 99. The net change is 100 to 99, a decrease of 1%.
\[ \begin{aligned} &\left(1 + \frac{10}{100}\right)\left(1 - \frac{10}{100}\right) \\ &= 1.1 \times 0.9 = 0.99 \end{aligned} \]
The shortcut for an equal rise and fall of \(x\)% is a net fall of \(\frac{x^{2}}{100}\)%. 0% is the trap of assuming the two changes cancel; they do not, because the decrease is taken on a larger base.
A and B can do a work in 8 days, B and C can do the same work in 12 days, and A, B, and C can do it in 6 days. In how many days can A and C do it?
Your Answer : (Not Answered)
Correct Answer : C
One day's work: (A+B)=1/8, (B+C)=1/12, (A+B+C)=1/6. A's work = (A+B+C) - (B+C) = 1/6 - 1/12 = 1/12. C's work = (A+B+C) - (A+B) = 1/6 - 1/8 = (4-3)/24 = 1/24. (A+C)'s one day work = 1/12 + 1/24 = (2+1)/24 = 3/24 = 1/8. So, A and C can do the work in 8 days.

Statement: Kartik left for Delhi on Tuesday by train to attend a function to be held on Friday at his uncle's house in Delhi.
Assumptions:
1. Kartik may reach Delhi on Wednesday.
2. Kartik may reach Delhi before Friday.
Your Answer : (Not Answered)
Correct Answer : B
Clearly, it cannot be deduced as to which day Kartik would reach Delhi. But Kartik has left for Delhi to attend a function to be held on Friday. So, he must have planned his journey to reach Delhi before Friday. Thus, only II is implicit.

Ozone - layer is getting depleted because of
Your Answer : (Not Answered)
Correct Answer : C
The ozone layer is depleted by man-made compounds containing both fluorine and chlorine.
Chlorofluorocarbons drift up to the stratosphere, where ultraviolet light frees a chlorine atom that then destroys ozone catalytically: \[\mathrm{Cl + O_3 \rightarrow ClO + O_2},\qquad \mathrm{ClO + O \rightarrow Cl + O_2}\] One chlorine atom can destroy tens of thousands of ozone molecules before it is removed.
Your Answer : (Not Answered)
Correct Answer : A
The kilowatt-hour is a unit of energy.
It is power multiplied by time, so \[1\ \mathrm{kWh} = 1000\ \mathrm{W} \times 3600\ \mathrm{s} = 3.6\times10^{6}\ \mathrm{J}\] The kilowatt is the unit of power; the electricity bill charges for energy consumed, which is why the meter counts kilowatt-hours.
Your Answer : (Not Answered)
Correct Answer : D
An object weighs least at the centre of the earth, where it weighs nothing at all.
There the mass of the earth surrounds it equally in every direction, so the pulls cancel exactly and \( g = 0 \). Weight is greatest at the poles, where the radius is smallest and there is no rotational effect.

Your Answer : (Not Answered)
Correct Answer : C
They belong to Buddhism.
The Jatakas are 547 stories of the Buddha's former births, in the Khuddaka Nikaya of the Pali canon. They are also a rich source for the social and economic life of early India, and their scenes are carved at Bharhut and Sanchi.
Which of the following food grain crops occupies the largest part of the cropped area in India?
Your Answer : (Not Answered)
Correct Answer : C
Rice occupies the largest share of the cropped area.
It is grown on about 44 million hectares, chiefly in the eastern and southern states where rainfall exceeds 100 cm, followed by wheat at about 30 million hectares in the north-west. India is the second largest producer of both.
C Programming [ Question No: 14 To 17 ] :
Literal means
Your Answer : (Not Answered)
Correct Answer : B
Correct answer: a string constant
In C a literal is a constant written directly in the source, and "string literal" means a string constant - a sequence of characters in double quotes, stored as an array of char with a terminating null appended by the compiler.
The term is worth distinguishing from a string in general, which may be held in a modifiable array. A string literal is not modifiable: attempting to write through a pointer to one is undefined behaviour, and identical literals may share storage.
#include <stdio.h>
#define X 3
#if !X
printf("Geeks");
#else
printf("Quiz");
#endif
int main()
{
return 0;
}
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Compiler Error
The #if is evaluated correctly - X is 3, so !X is 0 and the #else branch survives. But what survives is the line printf("Quiz"); sitting at file scope, outside any function, where only declarations are allowed. The compiler rejects it. Conditional compilation chooses which text reaches the compiler; it does not excuse that text from the language rules.
What is the output of this program?
#include <stdio.h>
#include <stdlib.h>
int main()
{
struct test
{
int i;
float f;
char c;
};
struct test *ptr;
ptr = (struct test *)malloc(sizeof(struct test));
ptr ->f = 2.5f;
printf("%f", ptr->f);
return 0;
}
Your Answer : (Not Answered)
Correct Answer : B
Here test is a structure name which consist of three variables of three different data types. ptr is the pointer variable, for which the memory is allocated dynamically by using malloc() of function and then it is pointed towards the structure floating variable f. Now f is initialized with a value 2.5f and then outputted as 2.500000.
Algorithm and Flow chart help us to
Your Answer : (Not Answered)
Correct Answer : D
Correct answer: Specify the problem completely and clearly
An algorithm sets out the steps of a solution in order, and a flowchart shows the same thing diagrammatically. Both exist to make the logic explicit before any code is written - which is where ambiguities and missing cases come to light. Neither has anything to say about memory, number bases or printers.

In OLE DB, actions that an object can perform are called:
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: methods.
In the object model an object has properties, which are the characteristics it exposes, and methods, which are the actions it can perform. A collection is an object that contains a group of other objects. The vocabulary matters because an OLE DB interface is defined precisely as the set of objects it exposes together with their properties and methods.
Digital Electronics [ Question No: 19 To 19 ] :
Match List – I with List – II and select the correct answer by using the codes given below the lists :
| List – I | List – II |
|---|---|
| a. Multiplexer | 1. Sequential memory |
| b. De-multiplexer | 2. Converts decimal number to binary |
| c. Shift-register | 3. Data Selection |
| d. Encoder | 4. Routes out many data input with single data output |
Codes : a b c d
Your Answer : (Not Answered)
Correct Answer : B
The key matches the multiplexer with the item that routes many data inputs to a single data output, so a matches 4, and the de-multiplexer with data selection, so b matches 3. The shift register is a sequential memory, so c matches 1, and the encoder converts a decimal number into binary, so d matches 2. The code is 4 3 1 2. The first option, 3 4 1 2, interchanges the first two pairs, which would call the multiplexer the data selection element and the de-multiplexer the many-to-one device, and the key does not accept that. The answer is 4 3 1 2, as the key has it.
Engineering Mathematics [ Question No: 20 To 20 ] :
The differential equation \(\frac{d^{2}y}{dx^{2}} + 16y = 0\) for \(y(x)\) with the two boundary conditions \(\left.\frac{dy}{dx}\right|_{x=0} = 1\) and \(\left.\frac{dy}{dx}\right|_{x=\frac{\pi}{2}} = -1\) has
Your Answer : (Not Answered)
Correct Answer : A
The problem has no solution.
The general solution is \(y = A\cos 4x + B\sin 4x\), so \(y' = -4A\sin 4x + 4B\cos 4x\).
\[ \begin{aligned} y'(0) &= 4B = 1 \Rightarrow B = \tfrac{1}{4} \\ y'(\pi/2) &= -4A\sin 2\pi + 4B\cos 2\pi = 4B = 1 \end{aligned} \]
The second condition demands -1, but every solution gives y'(\(\pi\)/2) = 1, so the two conditions contradict each other.
If the second condition had been +1, A would be free and there would be infinitely many solutions; a linear problem like this can never have exactly two.
