Khwaabo Ki Awaz

Dil bhi ajib cheez hai ,
Jise jaisa samajhta hai woh waisa hota nahi.
Khwaab har pal naye bunta rehta hai,
Par har khwaab pura hota nahi.

Parakhta hai har insaan ko ek mapdand par,
Par sabka ek jaisa bhaar nahi.
Kyunki tolta hai jis traaju par, 
Uska toh hota koi mol nahi.

Har ek aadmi ahem main choor hai,
Main mera mujhse hata nahi.
Par woh yeh bhool jaata hai ki,
Iss duniya par uska raj chal sakta nahi.

Kisko kya-kya hum samjhayein,
Apne mein hi toh khot bhari.
Patjhar main patte pedo se gir jaayein,
Ismein pato ka toh koi dosh nahi.

Important Fractions And Ways To Remember

Double denominator percentage halfed :

1)   1/2   =  50 %           1)   1/7  =  14.28 %       1)  1/11  =  09.09 %

2)   1/4   =  25 %           2)  1/14 =   07.14 %       2)   1/22  = 04.54 %

3)   1/8   =  12.25 %

4)   1/16 =  06.25 %   & so on...

Triple denominator percentage will be one third :

1)   1/3  =   33.33 %

2)   1/9  =   11.11 %   & so on...

Following a pattern :

1)        1/19            1/20                 1/21  (.25 corresponding to 5^2)
 5+.25= 5.25 %          5 %        5-.25= 4.75 %  

2)        1/24            1/25                 1/26   (.16 corresonding to 4^2)
 4+.16= 4.16 %          4 %        4-.16= 3.84 %

Others : 

1)  1/6   = 16.67 %            1)  1/12 = 8.33 %          1)  3/8  = 37.5 %

2)  1/15 = 06.67 %

Management Point Puzzle

Q. If your company manager calls you and tell you that he want to discuss about the pay hike and give you two options: (Assumption : You are going to work for atleast next 2 years )

i) tht he will increase your salary by 19% this year and will decrease the salary by 11% next year.
ii) tht he will decrease the salary by 11% this year and will increase your salary by 19% next year.
Wht option will have greater amount which will be base for 3rd year hike?

Ans

If we closely look to the option both are same:

succesive increment and decrement  leads to 

19-11-19*11/100=19-11-2.09= 5.91%  
OR
-11+19-19*11/100=5.91%

So 5.91% increment in total for both the case.

Hide your folder

To hide folder completely or making it invisible( jadooo... :) ), 

follow two simple steps --

First :-  Make folder name invisible

• Right click on folder that you want to be hide, choose “Rename” option.
• Now hold down “ALT” key and type 0160 or 255 right side number keypad.
• Now release "ALT" key and click "ENTER".
• Now you can see that there is no folder name for our specific folder.

Second :- Make folder icon invisible.

• Right click on your folder 

1. >> Select Properties >> 
2. >> Select Customize tab >> 
3. >> and here click on Change icon.

• You will see some icons without any kind of images, choose it and click ok.

Kahaani Dosti Ki

Paheli dosti ki hai badhi mazedar,
koi banta hai bevkuf toh koi bana samajhdar.
humne ki nahi khata use kabhi suljhane ki,
kyunki paheli hoti hi hai dusro ko uljhane ki.

Sachi dosti kar ke jab ek bar main haara tha,
uske bad din aur rat ka farak hi nahi pata chalta tha.
syllabus padh padh pura kar diya thodhe hi dino mein,
ghar waale dar gaye ki Einstein toh nahi aa gaya ismein...:)

Exam main baitha poore confidence se main,
kahan aate the last aur aa gaya class me first main.
usi dost ne pucha aisa tumne paper main kya khaya tha,
humne usse kaha ki dosti ka 'Power Pack' tumne hi to dalwaaya tha... :)

Interesting facts about Java

1) Think for the output and analyse:

public class CheckOutput 
{
public static void main(String args[])
{
System.out.println(2+2+"="+2+2);
}
}

Ans : Output
4=22
Note:

as Java starts treating everything as a String once it has encountered a string in System out statement.

Digit sum VS Sum of digits + JAVA Code

Sum Of Digits : It is the sum of all the digits of a number(given) and we are list bothered about the result.

Eg.  Given Number   ->   5982

       Sum of digits     :    5+9+8+2 =24             Result is 24

       Note : 

       Here, result can be a single digit or multiple digit.

Digit Sum : It is also the sum of digits but we have to add the digits till it become a single digit number.

Eg.  Given Number->  5982

       Digit sum       :   5+9+8+2 = 24 but we have to sum the digits again as 24 is not a single digit

                                2+4=6                          Result is 6

       Note:

       Here, final result will always be as single digit number.

(Shortcut to get Digit sum)

Digit sum is the remainder we get after dividing the number by 9

eg.   5982%9  = 6    where % specifies modulus used to find remainder.    


JAVA Code for Sum of Digits

public class sumOfDigits
{
public static void main (String args[])
{
int number =5982;
int sum=0;
int variable;
while(number>0)
{
variable=number%10;
sum=sum+variable;
number=number/10;
}
System.out.println("Sum of Digits is : "+sum);
}
}  


JAVA Code for Digit Sum


public class DigitSum 
{
public static void main (String args[])
{
int number =5982;
int sum=0;
int variable;
while(number>9)
{
while(number>0)
{
variable=number%10;
sum=sum+variable;
number=number/10;
}
number=sum;
sum=0;
}
System.out.println("Sum of Digits is : "+number);
}
}             

       

Simple puzzles

Q1 We have trees in all 26 rows and 26 columns. And we want to put a golden flower in between any two trees So can you tell us the number of flowers needed to buy so that they can be planted.

Ans  : we have three concerns to find the number of flowers
         i.  Rows(R)
         ii. Columns(C)
         iii.Diagonal alignment(D)
         So, Number is     26*25(R)+26*25(C)+25*25(D)
