leisurely. the hare and tortoise meet when the hare has covered only 1/8 of the
distance.by what factor should the hare increase its speed so as to tie the
NOTE: The trick for this question is that the answer
with the decimal is wright because the software has some flaw which gives a
decimal in this question. But it’s not with other questions.

B.while water fills at the rate of one litre every hour in A,it gets filled up
like 10,20,40,80,160...in tank B.(at the end of first hour,B has 10 litre.second

5. Alok and Bhanu play the following min-max game. Given the
N = 12+X*(Y-Z) Where X, Y and Z are variables representing single digits (0 to
9), Alok would like to maximize N while Bhanu would like to minimize it. Towards
this end, Alok chooses a single digit number and Bhanu substitutes this for a
variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu,
the variable to substitute the value. Finally Alok proposes the value for the
remaining variable. Assuming both play to their optimal strategies, the value of
N at the end of the game would be -

formulaes for this kind of question:
Directly put the value and find the answer

23. Alice and Bob play the following coins-on-a-stack game.
20 coins are stacked one above the other. One of them is a special (gold) coin
and the rest are ordinary coins. The goal is to bring the gold coin to the top
by repeatedly moving the topmost coin to another position in the stack.
24.Alice starts and the players take turns. A turn consists
of moving the coin on the top to a position i below the top coin (0 = i = 20).
We will call this an i-move (thus a 0-move implies doing nothing). The proviso
is that an i-move cannot be repeated; for example once a player makes a 2-move,
on subsequent turns neither player can make a 2-move.
If the gold coin happens to be on top when it's a player's turn then the player
wins the game. Initially, the gold coinis the third coin from the top. Then
a. Alice has no winning strategy.
b. In order to win, Alice's first move should be a 1-move.

After the technical round he said that he wanted to test
my management skills so he gave me a situation and asked me how to handle the
situation…The situation given was -
Suppose you are a project leader and under you a junior works
who has a habit of drinking to the brim everyone in the office hates him. And
you cannot fir him out of the office because he is a hard worker and no project
can we done well without him. He doesn’t obey his senior also he shouts if
someone wants to talk to him. But the main thing is that he is a good programmer
and nothing can be done well without him then what will u do.
In this round the interviewer was jumbling the situation after giving new
answer. After each answer he asked new questions.
After my second interview in my HR round the interviewer
asked all the members to form a circle and he gave a topic and made us to do a
debate and asked us that we should not talk anything negative abt anyone.
The topic was:
Suppose out of you five I have to choose only one member then start the debate.
This was all the three rounds which I faced.
Final selection was 195 out of 268.i was finally selected for the TCS.
