TCS PLACEMENT PAPERS ON 17th MARCH AT BHUBANESWAR : :

hi…i am Akhilesh thakur from KRUPAJAL ENGG COLLEGE, bhubaneswar.we were having on campus drive of TCS on 17 & 18 march 2008.All together there were 230 students were there,184 cleared the written test and finally 78 got through the Campus,And I was one of them. All the aptitude questions were repeated from previous year papers from TCS.For critical reasoning section go through the GRE 12th edition,it is available on the net.Even if u r not able to solve that just mug up the answers.

First there will be PPT frm TCS then they will give u the details of online test.there is no sectional cut off ,attempt as much question frm aptitude section,as most of them are repeated

There will be three section

1.English 32 ques 20min
2.Aptitude section 38ques 40 min.
3.critical reasoning 12ques 30min.

QUANTITATIVE APTITUDE SECTION

1. Two pencils costs 8 cents, then 5 pencils cost how much
Sol: 2 pencils è 8 cents => 1 pencil è 4 cents
Therefore 5 pencils cost = 5 * 4 = 20 cents

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.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
ð 2X + ¼ = 4 ½ => 2X = 4 ½ – ¼ => 2X = 4 ¼ => X= 2. approx
Therefore the fuel consumed while coming = 2 gallon

4. 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.

5. A person, who decided to go to weekend trip should not exceed 8 hours driving in a day. Average speed of forward journey is 40 m/h. Due to traffic in Sundays, the return journey average speed is 30 m/h. How far he can select a picnic spot?
a) 120 miles
b) Between 120 and 140 miles
c) 160 miles
Answer: 120 miles

5. 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

6.A bus started from bus stand at 8.00am, and after 30 minutes staying at destination, it returned back to the bus stand. The destination is 27 miles from the bus stand. The speed of the bus is 18mph. In return journey bus travels with 50% fast speed. At what time it returns to the bus stand?
Sol: 11.00am

7.In a mixture, R is 2 parts S is 1 part. In order to make S to 25% of the mixture, how much r is to be added?
Sol: One Part

8. Wind flows 160 miles in 330 min, for 80 miles how much time required.
Sol:

9. With 4/5 full tank vehicle travels 12 miles, with 1/3 full tank how much distance travels
Sol: ( 5 miles )
