There are 2 stage for it.

1st is written test which consist of 35 aptitude questions which are very very easy. Because most of the questions are calculation type and formula based and also calculator is allowed during test. I have answered 27 questions out of 35.

My suggestion is please ateend minimum 25 questions. Remember there is negative mark for wrong answer. So answer very carefully. After this there is Tecnical Interview it is also some what easy. They ask you questions from each subject. So be prepare for it. So please answer carefully.

Aptitude questions(35)
1. 6 persons standing in queue with different age group, after two years their average age will be 43 and seventh person joined with them. Hence the current average age has become 45. Find the age of seventh person?
Solution:  It is given as after 2 year average age wiil be 43 so now the average is 2 year.

After addition of 7th person average is 45 so 7th person wiil be 45+(6*(45-4))

Ans: 69

2. Horse started to chase dog as it relieved stable two hrs ago. And horse started to ran with average speed 22km/hour, Horse crossed 10 mts road and two small pounds with depth 3m, and it crossed two small street with 200 mts length. After traveling 6 hours, 2hours after sunset it got dog. Compute the speed of dog?

Ans: As we have speed and travel time of horse, we can get distance travelled by it.
Hence d = 22*6 = 132km,
Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier).
Hence speed of dog = 132/8 = 16.5km/hr

3. 3, 22 , 7, 45, 15, ? , 31
Solution: Here it appear simple, because it arranged in arranged in sequence manner, but the actual question was some what twist mentioning fibonacci series and more over question was in statements (no numbers). Hence first try to understand the question well.
Here let group alternate terms 3,7,15,31 (3+4 =7, 7+8 =15, 15+16=31)
Similarly for second group (22,45,? (22+23 = 45, 45+46 = 91) hence ans is 91.

4. In Tnagar many buildings were under residential category.for buildings they number as 1 to 100. For shops, corporation numbered between 150 and 200 only prime numbers. how many time 6 will appear in building numbering?
This type of question if it is asked how many 2,3,4,5,6,7,8,9 then you bindly write the answer as 20. But for 1 answer will be 21 as 100 is included

5. ((4x+3y)+(5x+9y))/(5x+5y) = ? as (x/2y) = 2
Ans: as x=2y put the value and get the answer.

6: If we subract a number with y, we get 4 increase of number, once it got divided by y itself. Find that number?
Ans: 12 (we can easily predict from options, as we take y as 6)

7. I don’t remember exactly the question, one logical problem stating the colour of beer?
Ans: white. What ever the question about the color of beer means you wrote the answer as white because polar beer. This question is very lengthy don’t burther about that.

Ans: Bird(category)

9. One question like. (209*144)^2 + (209*209)+(209*144)+(144*144) = ?
Ans: here you can use calc, many(4 to 5) questions were depend upon calc alone.(no need problem solving technique).

10. I’m only son for my parents. (some irrelevant statements in the middle to distract you). The man in picture is my father’s son (some irrelevant statements). Who is he?
