There is an island. Its inmates speak only two sentences at a time. Out of those two sentences, one is right and one is wrong. You go to that island and meet 4 inmates Ram, Sita, Laxman and Hanuman.

You: Whose wife is Sita?
Ram: Sita is the wife of no one. Sita is married to my brother.
Sita: Laxman is my husband. I am married to Hanuman.
Laxman: Sita is unmarried. Ram is not my brother.
Hanuman: I don't talk with strangers. Sita is not unmarried.

pretty simple. Whose wife is Sita?

Another one:

Imagine you have gone to China (from Chandni Chowk, ofcourse) and you have learnt "talwarbaazi" over there. Now you are faced with a dragon and you are supposed to kill it. The dragon has 3 heads and 3 tails. A dragon is considered dead if ALL heads and ALL tails are chopped off. But this dragon is nasty. Here are the conditions:

1) If 1 head is chopped off, 1 extra head grows.
2) If 1 tail is chopped off, 2 extra tails grow.
3) If 2 tails are chopped off together, 1 head grows.
4) If 2 heads are chopped off together, nothing grows.

So what is the minimum number of 'slashes' required to kill the dragon?

this is also preety simple. remember "MINIMUM NUMBER OF SLASHES".

I got the answer.It is damn simple.

1)In First Shot he cut 2 heads together so nothing grows.
Now dragon has 1 head , 3 Tails .
2)next shot he cut 2 tails , so another head grows.
Now 2 heads , 1 tail.
3)He cuts 1 tail so that 2 tails grow.
now 2 heads , 2 tails
4)he cut once again 1 tail so that 2 grows
now 2 heads , 3 tails
5)another 1 tail gone so that 2 tails grow
now 2 heads , 4 Tails
6)He cut 2 tails , 1 head grows
Now 3 heads , 2 tails
7)He cut another 2 tails so 1 head grows
Now 4 head and no Tail :D
8)He cut 2 heads nothing grows.
Now 2 heads and no tail
9)Again he cut 2 heads and nothing grows.
