TCS PAPER ON 29TH FEBRUARY AT GCE,SALEM
Hi friends,
I want to tell sincere thanks to FRESHERSWORLD.COM because it will help to be placed in TCS.
QUANTITATIVE APTITUDE SECTION
1. A man, a woman, and a child can do a piece of work in 6 days. Man only can do it in 24 days. Woman can do it in 16 days and in how many days child can do the same work?
Ans: 16
2. A work is done by two people in 24 min. one of them can do this work a lonely in 40 min. how much time required to do the same work for the second person.
Sol: (A+B) can do the work in = 1/24 min.
A alone can do the same work in = 1/40 min.
B alone can do the same work in = (A+B)’s – A’s = 1/24 – 1/40 = 1/60
Therefore, b can do the same work in = 60 min
3. Low temperature at the night in a city is 1/3 more than 1/2 high as higher temperature in a day. Sum of the low temperature and highest temp. is 100 degrees. Then what is the low temp?
Sol: 40 deg.
4. A person was fined for exceeding the speed limit by 10mph. Another person was also fined for exceeding the same speed limit by twice the same. If the second person was traveling at a speed of 35 mph, find the speed limit.
Sol: Let ‘x’ be the speed limit
Person ‘A’ was fined for exceeding the speed limit by = 10mph
Person ‘B’ was fined for exceeding the speed limit by = twice of ‘A’
= 2*10mph=20mph given that the second person was traveling at the speed of 35mph => 35mph – 20mph = 15mph
Therefore the speed limit is =15 mph
5. A finishes the work in 10 days & B in 8 days individually. If A works for only 6 days then how many days should B work to complete A's work?

32. A car is filled with four and half gallons of oil for full round trip. Fuel is taken 1/4 gallon more in going than coming. What is the fuel consumed in coming up?
Sol Before the trip, car is filled with = 4 ½ gallon of oil
Let ‘X’ be the quantity of fuel consumed for the trip in one direction
The fuel consumed while going = X + ¼
The fuel consumed while coming = X
Therefore, the fuel consumed for the trip = (X + ¼) + X = 4 ½

HR+TECH INTERVIEW:
I had technical interview on march 1st .i am waiting for technical interview from morning 8’o clock but they called only me at evening 6’o clock……Before go to attend the interview I refresh myself and relax me.
For technical round, get well dressed in formal outfits. Bring the file with Ur certificates and Resumes. Don’t bluff in the resumes, as they check your resume and ask questions related to it.
Surely they asking questions from the resume only pls go through it…
For me two interviewers were there.

ME: sir just I only known the basics in C sir.
INT2: ok nothing problem Ur from non-it we will train u.
INT1: (then they asked) which is Ur favourite subject?
ME: I told digital electronics
INT1: what r the basic gates present in that?
ME: answered.
INT1: why we called NAND and NOR gate as UNIVERSAL GATE?
ME: answered.
INT1: what is the difference between open collector and TTL circuit?
ME: answered.
INT1: again he asked to draw that one?
ME: I drawn.
INT1: ok ok well…..
INT2: what is Digital Image processing?
ME: answered.

INT2: I want to transmit high frequency image how?
ME: answered.
INT2: how I select particular part from the image?
ME: answered.
INT2: ok ok well.
INT1: what is an embedded system?
ME: answered.
INT1: tell some real time applications?
ME: I tell so many things they excited.
INT2: what is kirchoffs law?
ME: answered.
INT2: tell superposition theorem?
ME: answered.
INT1: tell me about urself.
ME: I told some thing in that explained about my paper presentation.
INT1; Which Topic
ME: NANOTECHNOLOGY
INT1: explained shortly.
ME: I explained advantage and applications about my project...
INT1; wow, nice well……
INT2: Through these paper presentations what u learned?
ME: yes sir initially I removed my stage fear, and improve my communication skill , presence of mind, and my listening skills...

In that also two of interviewers …
INT: get in
ME: good evening sir
INT1: tell me about yourself
ME: I explained.
INT2: why not u can go for higher studies.

INT1: what is Electronics? And what is Communication?
ME; answered
INT2: list some communication/
ME: I listed …
INT2: ok fine ………..
Again I wish to both and gave handshake with smile…….
My best advice before going to attend TCS interview u should go through previous year placement papers .surely its enough to clear the aptitude and refer BARRON’S 12 TH EDITION it will help to clear the verbal ..and also u should go through the model question paper which is available in the Barron’s book………………………
All the best ……we will meet in TCS…..
