Who invented Input device MOUSE?
Q 4.
What are the origins of the Internet?
Q 5.
Write a C program such that after execution it will delete itself. And you cannot find the file in the directory listings? 
bhargava.meghaC program code
int zap(int n)
{
if(n<=1)then zap=1;
else zap=zap(n3)+zap(n1);
}
then the call zap(6) gives the values of zap
[a] 8 9 [c] 6 [d] 12 [e] 15

1. I think the next palindrome should be 14041. So speed of car becomes 55 km/h. Correct?bhargava.meghaQ 1.

Sachin JainDeepika Can you give some explanation.
As i think there should be some technical reason behind this dissimilar thing. 
Deepika BansalBlunderBoy just notice the first three digits of each number:
a) 1284566678
b) 1234566678
c) 1284566878
d) 1284566678
So the answer is b. 
bhargava.megha
I think u r right but PLEASE EXPLAIN YOUR ANSWER ,HOW IT IS.......blunderboyAnd ZAP(6)=9 
makru921
Deepika, why can't we look at the last 3 digits of the numbers? In that case the answer would be (C). Right?Deepika BansalBlunderBoy just notice the first three digits of each number:
a) 1284566678
b) 1234566678
c) 1284566878

But I think these type of questions are solved like this only. I did it that way only.

X,Yand Z are senior engineers. A,B,C,D are junior engineers. Company wants to select 4 enginers. Two will be senior and two will be juniors. The company wants these engineers to work in the most productive way so they respect each person's likes/dislikes.
Y is not friends with A
Z is not friends with C
B is not friends with A
If B is selected then who will be the remaining 4 members ?
If C is selected, Z and ___ cannot be selected?
D is always selected if ___ is selected?

If the letters of the word "rachit" are arranged in all possible ways and these words are written
out as in a dictionary, what is the rank of the word "rachit".
(a) 485
(b) 480
(c) 478
(d) 481 
Sachin Jain@ Deepika
Thanks for your answer
But i do not know why i can't find satisfaction by this answer.
We can also say the option should be C as the last three digits are different in that.
a) 1284566678
b) 1234566678
c) 1284566878
d) 1284566678

Solutionbhargava.meghaQ
A speaks truth 70 % of the times, B speaks truth 80% of the times.
What is the probability that both are contradicting each other is ?
here "%" is %
Give your answer with EXPLANATION...........
Prob of A speaking truth : 0.7
Prob of A speaking lie : 0.3
Prob of B speaking truth : 0.8
Prob of B speaking lie : 0.2
So Prob of contradicting each other : 1  (They will agree to same answer)
=> 1  (0.7*0.8)
10.56
So answer will be 0.44
correct me if i am wrong 
Sachin Jain
Answer to this will be 481bhargava.meghaQ
If the letters of the word "rachit" are arranged in all possible ways and these words are written
out as in a dictionary, what is the rank of the word "rachit".
(a) 485
(b) 480
(c) 478
(d) 481
Solution :
a _ _ _ _ _ = Total words 120
c _ _ _ _ _ = Total words 120
h _ _ _ _ _ = Total words 120
i _ _ _ _ _ = Total words 120
So now letters in dictionary will start from r
first word starting with r will be rachit.
So rank is 481

Given that : F(1)=1 ,F(0)=1, F(1)=1, F(2)=1bhargava.meghaI think u r right but PLEASE EXPLAIN YOUR ANSWER ,HOW IT IS.......
Now,F(n)=F(n3)+F(n1)
You can solve this by using making characteristic equation, then solving it.
Since in this question , i just need to calculate F(6) so i did some manual calculation as:
F(1)=1
F(2)=1 + 1 =2
F(3)=1 + 2 =3
F(4)=1 + 3 =4
F(5)=2 + 4 =6
F(6)=3 + 6 =9
Thats how i got it. 
Sachin JainBut if we have to calculate F(100) then obviously you have to make characteristic equation and then F(100).

I think we should also consider the fact that they can also lie at the same time. Buddy you haven't considered that. Probability of (A'^B) & (A^B') should be considered, so ans. will be P(A'^B)+P(A^B') which comes to 0.38 by considering independent events. i.e. they contradict 38% of the times.blunderboySolution
Prob of A speaking truth : 0.7
Prob of A speaking lie : 0.3
Prob of B speaking truth : 0.8
Prob of B speaking lie : 0.2
So Prob of contradicting each other : 1  (They will agree to same answer)
=> 1  (0.7*0.8)
10.56
So answer will be 0.44
correct me if i am wrong 
Sachin Jain@ Shreya
Take this example..
What day is today ? { Suppose today is friday }
Prob of saying A friday is 0.7
Porb of B saying friday is 0.8
But if they both say false ,
A: tuesday
B: wednesday
They are both lying still they are both contradicting each other.
So i think we should subtract from 1 the prob when they same say truth.
PS: I know next comment will be.
You will say that when they both lie still they can say the same day.
Well then it depends on question for what they will be answering.

The most direct way is to use exponential generating function.
May be ping is the answer for the second Q. 
Kaustubh Katdare"Web browsing" is not an application. It's an activity, isn't it?

define with explanation!!!!!! 
Sumit Chandis it 549? if nt pls gve the ans and hw ?

Sumit Chandin case if i m wrong pls correct me! thnk there are 16 million colors implies 2^24, also 24bits means 3bytes.Thus answer for 1024*1280*3 = 4MB

please give ur answe with explanation!!!!
gud luck......
bcoz...
take 1 sqaure...divide it in four part.....
now divide each part in half diagonally....means each part will have two triangle......
so for 1 triangle it will be 1/8
