1)Distance b/w A and B is 36km.One person starts at A with speed 6kmph
and another from B with same speed.One dog starts at A with speed of
80kmph.All 3 start at same time.When the 2 persons met in the way,the
dog
stops.Then whats the distance travelled by dog?
Ans) 80*(36/(6+6))=80*3=240km.
2)There is one product which raises its cost to 25% in odd years and
falls down 20% in even years.Then After 10 years whether the cost of
that
product will raises or fall down?
Ans) Remains same. (If 'x' is present cost then in next year its cost
will be (5/4)*x and in later year it will be (4/5)*((5/4)*x)=x.So after
every 2 years cost will be same.
3)One train starts from bombay to amrutsar at 9am every day and reaches
its destination after 3 days and half hour more.And the same with the
train starting at amrutsar (starts at 9am and reahces 9:30am after 3
days).If a person travels from amrutsar to mumbai,howmany trains he
will
come across which goes towards amrutsar.
Ans)When he starts at amrutsar already 3 trains will be on the way.And
while he reaches mumbai 4 more trains will start.So he will come across
7
trains.
4)There is a rope of length 20m and it was cut into 2 parts and each
part
is shaped as periphery of a square.Then whats the probability that one
of
the square has area of 9 sq.meter.
Ans)I dont the answer to this question but its very good questions and
this type of questions may be asked even in interview.So try to get
answer to this question.
5)There is one block of houses with numbers from 1 to 82.
Renu wants to take interview of bhanu.But renu dont know exactly
bhanu's
house number but she remembered some hints about that number.She met
bhanu's little genious brother at the entrance of block.She asked him
abt
the number with the following questions.
a)Is the number under 41.
b)Is it divisible by 4.
c)Is it a square number.
The little boy replied either yes or no to the above questions.
Then renu got the house number.Whats that number.
Ans)Let that number be perfect square so that we can filter out nore
numbers.And the perfetc squares divisible by 4 are 4,16,36,64.And if
that
number is above 41 then house number will be unique and that is 64.So
required answer is 64 and answers to a: no; b:yes; c=yes.
6)X is a quiz master and he asks questions to A,B,C.X asks 30 questios
to
each of A,B and C. And he got 45 correct answers.A got 55% of the B's
score and sum of A and C's scores was 25% more than B's score.Then
what's
the individual scores.
Ans)Let the score of B be 'p'.Then score of A is 0.55*p and C's score
was
1.25*p-0.55*p.then total score was: 2.25*p = 45.==>p = 20.
And i couldn't get the remaining questions which r very big. and refer
barrons(GRE) for last questions.
It takes less time to do a thing right than
it does to explain why you did it wrong.
