Q1. A contour line joins locations having the same height above the mean sea level. The following
is a contour plot of a geographical region. Contour lines are shown at 25m intervals in this
plot. If in a flood, the water level rises to 525m, which of villages P,Q, R, S,T get submerged
?
Answer : Option C
Explaination / Solution:
The given contour is a hill station, the peak point of this hill station is P, it is under a contour
of 550 . At floods, the water level is 525m. So the village of R, S and T are under a contour of
500. Therefore these villages are submerged.
Q2. The expression ((x + y) - |x - y|)/2 is equal to
Answer : Option B
Explaination / Solution:
Q3. Six people are seated around a circular table. There are at least two men and two women .
There are at least three right-handed persons. Every woman has a left-handed person to her
immediate right. None of the women are right-handed. The number of women at the table is
Answer : Option A
Explaination / Solution:
Out of six people, 3 place definitely occupied by right handed people as atleast 2 women are
there so these two will sit adjacently. Now as only one seat is left it will be occupied by a left
handed man because on right side of this seat is sitting an right handed man.
Therefore, answer should be 2 women.
Q4. Consider a company that assembles computers. The probability of a faulty
assembly of any computer is p. The company therefore subjects each
computer to a testing process. This testing process gives the correct result for
any computer with a probability of q. What is the probability of a computer
being declared faulty?
Answer : Option D
Explaination / Solution:
No Explaination.

Q7. The weight of a sequence a0, a1,…,an-1 of real numbers is defined as a0 + a1/2 + ..... + an-1/2n-1. A subsequence of a sequence is obtained by deleting
some elements from the sequence, keeping the order of the remaining elements
the same. Let X denote the maximum possible weight of a subsequence of
a0, a1,..., an-1. Then X is equal to
Answer : Option D
Explaination / Solution:
No Explaination.

What is the minimum possible weight of a path P from vertex 1 to vertex 2 in this
graph such that P contains at most 3 edges?
Answer : Option D
Explaination / Solution:
No Explaination.
