Hi this is jaya
The aptitude of TCS is as follows
1.The pace length p is the distance between the rear of two consecutive footprints.for men the formula n/p=123,gives an approximate relationship b/w n and p.where n=no. of steps per min,p=pace length in meters.bernard know his pacelength is 81cm.t formula applies to bernard walking.caluculate bernards walkin in kmph
Sol:x=n/p
Formula:(x*p2*60)/107
2.exp(m,n)=m power n, exp(10,m)=n*exp(2,3) then n=? ans:125
3. 12 men,12 lines,12min then 60 men,60 lines,How much time?
4.same as above but asked how many programmers/men?
5. 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.
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 provision 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 coin is the third coin from the top. Then

9.one student have to get 71%
For 300 marks he scores 237.final exam is for 100 marks.how many marks he should get to get 71%?
Ans:47
10.Average speed
Sol:2xy/(x+y)
11.given a long story
D=4*(t-11)
T=41
We think * as root but the answer is not matched for root.so I have taken that as * only.Then the answer is 120

22. Alok and Bhanu play the following coins in a circle game. 99 coins are arranged in a circle with each coin touching two other coin. Two of the coins are special and the rest are ordinary. Alok starts and the players take turns removing an ordinary coin of their choice from the circle and bringing the other coins closer until they again form a (smaller) circle. The goal is to bring the special coins adjacent to each other and the first player to do so wins the game. Initially the special coins are separated by two ordinary coins O1 and O2. Which of the following is true ?
