Here are the questions that appeared in the test. I tried to give the exact words from the test & I think I did well. Also I had given detail answers.
Q.1) Dr. Watson has 5 nephews. After he died he mentioned in his will that each of his brother's sons should get money according to their ages. The difference between each son is Rs. 20 & youngest son got least money. Total money to be shared is 1000. How much youngest son will get?
Ans:
Let the third i.e. middle son will get Rs. x then youngest son will get Rs. x40.
=> Adding their shares = 1000
=> (x40) + (x20) + x + (x+20) + (x+40) = 1000
=> x = 200
=> x  40 = 160
=> Youngest son will get Rs.160
Q.2) In a party there r total 1275 handshakes assuming each person did handshake with other fellow. How many people attended the party?
Ans:
Let number of people attended the party = x then
Number of handshakes =xC2 = 1275
=> x * (x  1) = 1275
2 * 1
=> x2  x  2550 =0
=> (x  51)(x + 50) = 0
=> x cannot be negative
=> x = Number of people attended party = 51
Q.3) If one fifth of a hive of bees flew to the rose flower, one third flew to the lotus flower, three times the difference of these two numbers flew to slandbara & one bee continued to fly about, attracted on each side by the fragrant of ketaki & malati, what was the total number of bees?
Ans:
X + X + 3( X  X ) +1 = X
3 5 3 5
=> X = 15 = Number of bees.
Q.4) Due to some defect in our elevator, I was climbing down the staircase. I had climbed down just 7 steps when I saw professor Zorkoski on the ground floor. Continuing to walk down, I greeted him & I was surprised to see that when I was yet to get down 4 steps to reach the ground floor, professor had already finished the climbing up 2 steps for every 1 of mine. How many steps did the staircase have?
Ans:
7 X 4
 
From figure, equation becomes : 7 + X + 4 = 2X
=> X = 11
=> Total number of steps = 7 + 11 + 4 = 22
Q.5) Complete the following series:
a) 3, 6, 13, 26, 33, 66, ?
Ans:
3 * 2 = 6
6 + 7 = 13
13 * 2 = 26
26 + 7 = 33
33 * 2 = 66
66 + 7 = 73
73 * 2 = 146
Series : 3, 6, 13, 26, 33, 66, 76, 146
b) 364, 361, 19, 16, 4, 1, ?
Ans:
364  3 = 361
O(364) = 19
19  3 = 16
O(16) = 4
4  3 = 1
O(1) = 1
1  3 = 2
Series: 364, 361, 19, 16, 4, 1, 1, 2
Q.6) A man was asked to meet a lady lawyer who had a good logical skill. Today is Saturday. A man wanted her appointment. She called her three days after the day before the day after tomorrow. What is the appointment day?
Ans:
Today = Saturday
Day after tomorrow = Monday
Day before the day after tomorrow = Sunday
Three days after the day before the day after the tomorrow = Wednesday
Therefore, Appointment day is Wednesday.

X Y G X Y G
+ 
A B A B
 
C D E F B G A

Q. 8) Somebody asked a wizard, Alchimiro about his age. He answered that he is still young according to age of wizards. Let me tell u, I m thrice my son's age & my father's age is 40 more than twice of my age. Total of our ages is 1240 years. What is the age of wizard?
Ans:
Let wizard's son age = X then wizard's age = 3X & his father's age = (6X+40)
=> X + 3X + 6X + 40 = 1240
=> X = 120
Wizard's age = 360 years
Q.9) This was 8 marks question regarding the committees of 5 juniors & 4 seniors they have to form 3 committees. Some conditions had given & based upon that we have to answer 4 questions. I solved it last. Sorry for not remembering the question.

Assuming the temperature to the nearest degree what are the temperatures on the five days in Celsius?
Ans: Temperatures on 5 consecutive days are: 2, 1, 1, 2, 3 in degree Celsius.
HR interview was cool. They didn't ask me to explain myself, a most imp question. Being a chemical engineer they keep asking me why you are not interested in chemical industry & what u did in last 1 year. I explained them all truly & they look convinced. So my advice is be true to them, they are among top mind readers. They will easily catch your bluffs. They asked me which concept from computer u like most. I told them about OOPS & explained it. They also asked me how u will adjust within a team. Such HR questions. Then they had given me a simple puzzle.
Well this is all about my Infosys experience. I am waiting for the result.
