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: Here the question appear as
an easy one, but carried a lot of unwanted sentences and unwanted datas(i dint
mention above) in exam which may confuse u on solving technique.
Let x be current average age of first 6
persons in queue and current age of seventh person be y. Then 6x will become the sum of those 6
persons age.
Now, let compute the sum of those 6
persons after two years, 6x+12 (as each and individual increase their age by
2). hence its average become (6x+12)/6 = 43 (give in question itself).
So now we can compute x from above
equation. (x = 41, 6x = 246)
Let now we compute y, ((6x+y)/7) = 45,
as we have value of x, compute y.
Ans: 69
121. Horse started to chase dog as it
relieved stable two hrs ago. And horse started to ran with average speed
22km/hr, 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 hrs, 2hrs 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
Ans:16.5km/hr.

Solution: Here the question appear as
an easy one, but carried a lot of unwanted sentences and unwanted datas(i dint
mention above) in exam which may confuse u on solving technique.
Let x be current average age of first 6
persons in queue and current age of seventh person be y. Then 6x will become the sum of those 6
persons age.
Now, let compute the sum of those 6
persons after two years, 6x+12 (as each and individual increase their age by
2). hence its average become (6x+12)/6 = 43 (give in question itself).
So now we can compute x from above

Q2) Paul the octopus who has been
forecasting the outcome of FIFA world cup matches with tremendous accuracy has
now been invited to predict ICC world cup matches in 2011. We will assume that

team in a group plays the other teams in the group. The top two teams from each
group enter the semi finals ( after which the winner is decided by knockout).

Q15) A research lab in Chennai requires
100 mice and 75 sterilized cages for a certain set of laboratory experiments .
To identify the mice, the lab has prepared labels with numbers 1 to 100 , by
combining tags numbered 0 to 9. The SPCA
requires that the tags be made of toxin-free material and that the
temperature of the cages be maintained at 27 degree Celsius. Also , not more

Question 1: There is a toy train that
can make 10 musical sounds. It makes 2 musical sounds after being defective.
What is the probability that same musical sound would be produced 5 times
consecutively? (1 of )?
Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 =
1/32
32 will be the answer. (My friends got
similar question with "3 times consecutively"; for that the answer
would be 8)
Question 2: Peter and Paul are two
friends. The sum of their ages is 35 years. Peter is twice as old as Paul was

Luckily, I had this question twice.
Initially I left it because of the confusing statement but when I got the same
question second time with different names of the friends (Pooja and Prasad)
then I gave a little extra time and solved it.
Answer: 20 years. I simply substituted
the answers in the statement to find the best fit, because the statement in the
question was pretty confusing.
Question 3: The ages of two friends is
in the ratio 6:5. The sum of their ages is 66.After how many years will the
ages be in the ratio 8:7?
Answer: 12 years.
Question 4: (There was a long story,
I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic,

conditions are to be followed: Lilac and Balsalmic go together. Woody and
Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added
with any material. (Actually they had also mentioned how much amount of one can
be added with how much quantity of the other; but that's not needed for the
question.) All of the following combinations are possible to make a perfume
except:
Balsalmic and Lilac
Woody and Lemon
Mimosaic and Woody
Mimosaic and Lilac
Answer: Mimosaic and Lilac. I have made
the question here really easy to understand. But the actual question was in a
twisted language and it was difficult to find the answer. It took me some time
to get to the answer.
