ROUND 2 APTI-MANIA

1. The length of the bridge, which a train 130 meters long and travelling at 45 km/hr can cross in 30 seconds, is:

Answer Explanation: Speed = (45 * 5/18) m/sec = (25/2) m/sec. Time = 30 sec. Let the length of bridge be x meters.

Then, (130 + X)/30 = 25/2 ==> 2(130 + X) = 750 ==> X = 245 m.

2. The number of arrangements that can be made with the letters of the word MEADOWS so that the vowels occupy the even places?

Answer Explanation:

The word MEADOWS has 7 letters of which 3 are vowels.

-V-V-V- As the vowels have to occupy even places, they can be arranged in the 3 even places in 3! i.e., 6 ways. While the consonants can be arranged among themselves in the remaining 4 places in 4! i.e., 24 ways.

Hence the total ways are 24 * 6 = 144.

3.A person was asked to state his age in years. His reply was, "Take my age three years hence, multiply it by 3 and then subtract three times my age three years ago and you will know how old I am." What was the age of the person?

Answer Explanation:

Let the present age of the person be x years. Then, 3(x + 3) - 3(x - 3) = x

3x + 9 - 3x + 9 = x => x = 18

4. [(√7 + √5) / ( (√7 - √5)] + [(√7 - √5) / (√7 + √5)] = ???

Answer Explanation:

[(√7 + √5) / ( (√7 - √5)] + [(√7 - √5) / (√7 + √5)]

= [(√7 + √5)2 + (√7 - √5)

2] / (√7 + √5)(√7 -

√5) [(√7 + √5)2 + (√7 - √5)

2] / 2 = 12

5.Albert buys 4 horses and 9 cows for Rs. 13,400. If he sells the horses at 10% profit and the cows at 20% profit, then he earns a total profit of Rs. 1880. The cost of a horse is:


Let C.P. of each horse be Rs. x and C.P. of each cow be Rs. y. Then, 4x + 9y = 13400 -- (i)

And, 10% of 4x + 20% of 9y = 1880 2/5 x + 9/5 y = 1880 => 2x + 9y = 9400 -- (ii)

Solving (i) and (ii), we get : x = 2000 and y = 600. Cost price of each horse = Rs. 2000.

6.

Number Puzzle: Which number replaces the question mark?

Answer: 100

Explanation:

(7+5)2 = 144; (3+4)2 = 49; (5+1)2 = 36.

So, missing number = (2+8)2 = 100.

B. 180 metres

C. 324 metres D. 150 metres

Answer: Option D Explanation:

5 50

Speed= 60 x

m/sec =

18 3

m/sec.

Length of the train = (Speed x Time).

50

Length of the train =

x 9

3 m = 150 m.

.

2. A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is:

A. 45 km/hr

B. 50 km/hr

C. 54 km/hr

D. 55 km/hr

Answer: Option B


Explanation: 125

Speed of the train relative to man = 10

m/sec 25

= 2 m/sec.

25 18

= 2

x 5 km/hr

= 45 km/hr. Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.

x - 5 = 45 x = 50 km/hr.

Round 4 Code Mania

What will be the output of the program? #include<stdio.h>

int i;

int fun();

int main() {

while(i) {

fun();

main(); }

printf("Hello\n");

return 0; }

int fun() {

printf("Hi"); }

A. Hello B. Hi Hello

C. No output

D. Infinite loop

Answer: Option A Explanation: Step 1: int i; The variable i is declared as an integer type. Step 1: int fun(); This prototype tells the compiler that the function fun() does not accept any arguments and it returns an integer value.


Step 1: while(i) The value of i is not initialized so this while condition is failed. So, it does not execute thewhile block. Step 1: printf("Hello\n"); It prints "Hello". Hence the output of the program is "Hello".

Round 2 Apti-Mania

1. Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

4 A. 4 %

7

5 B. 5 %

11

C. 10% D. 12%

Answer: Option B Explanation:

Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500. Selling Price (S.P.) = Rs. 5800.

Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.

Gain % = 300

x 100

= 5 5

%

5500

% 11

2. The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is: A. 15

B. 16

C. 18


D. 25

Answer: Option B Explanation: Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x. S.P. of x articles = Rs. 20. Profit = Rs. (20 - x).

20 - x

x 100 = 25 x

2000 - 100x = 25x 125x = 2000

x = 16.

60 x x = 420

100


x = 420 x 100

60 = 700.

1. Comparison between HTML and XML

2. Difference between ID selector and class selector in jQuery?

3. What is image map?

Answers 1.

HTML XML

HTML is an abbreviation for HyperText XML stands for eXtensible Markup Markup Language. Language.

HTML was designed to display data with XML was designed to be a software and

focus on how data looks. hardware independent tool used to transport

and store data, with focus on what data is.

HTML is a markup language itself. XML provides a framework for defining

markup languages.

HTML is a presentation language. XML is neither a programming language nor a

presentation language.

HTML is case insensitive. XML is case sensitive.

HTML is used for designing a web-page to XML is used basically to transport data


be rendered on the client side. between the application and the database.

HTML has it own predefined tags. While what makes XML flexible is that

custom tags can be defined and the tags are

invented by the author of the XML document.

HTML is not strict if the user does not use XML makes it mandatory for the user the

the closing tags. close each tag that has been used.

HTML does not preserve white space. XML preserves white space.

HTML is about displaying data,hence static. XML is about carrying information,hence

dynamic.

2. ID's are unique

• Each element can have only one ID

• Each page can have only one element with that ID

When I was first learning this stuff, I heard over and over that you should only use ID's once,

but you can use classes over and over. It basically went in one ear and out the other because it sounded more like a good "rule of thumb" to me rather than something extremely important. If

you are purely an HTML/CSS person, this attitude can persist because to you, they really don't

seem to do anything different.

Here is one: your code will not pass validation if you use the same ID on more than one

element. Validation should be important to all of us, so that alone is a big one. We'll go over

more reasons for uniqueness as we go on.

Classes are NOT unique

• You can use the same class on multiple elements.

• You can use multiple classes on the same element.

3. The <map> tag is used to define a client-side image-map. An image-map is an image with


clickable areas.

The required name attribute of the <map> element is associated with the <img>'s usemap attribute and creates a relationship between the image and the map.

The <map> element contains a number of <area> elements, that defines the clickable areas in the image map.
