(SET-3)

Company Name : TCS
Type : Fresher, Job Aptitude Test Paper

Hi Friends.

I have appeared for TCS on campus on 12th January at GNIT along with other 1300 students (JIS + Narula+ GNIT) .TCS had previously (in the month of December) given away their Demo paper to many colleges and we were no exception. We practiced them repeatedly. On the day of the aptitude test we found that each & every question in the aptitude was from those papers given previously by TCS. We were very happy, we answered around 28(correct) on an avg.
I personally answered 30(correct), could have answered >32 but didn’t due to the fear of uppercut off. In general cases it remains (lower cutoff 18 & upper cutoff >32).But Eventually when results were out.

SET : 3

1. Alok and Bhanu play the following min-max game. Given the expression N=40+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
(a) 49 
(b) 51 
(c) 31 
(d) 58

27. Alice and Bob play the following coins-on-a-stack game. 100 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. 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 (for some I between 0 and 100). We will call this an i-move (thus a 0-move implies doing nothing).
