The head of a newly formed government desires to appoint five of the six selected members P, Q, R, S, T and U to portfolios of Home, Power, Defense, Telecom, and Finance. U does not want any portfolio if S gets one of the five. R wants either Home or Finance or no portfolio. Q says that if S gets either Power of telecom, then she must get the other one. T insists on a portfolio if P gets one Which is the valid distribution of portfolios?

A
P-Home, Q-Power, R-Defense, S-Telecom, T-Finance
B
R-Home, S-Power, P-Defense, Q-Telecom, T-Finance

P-Home, Q-Power, T-Defense, S-Telecom, U-Finance
D
Q-Home, U-Power, T-Defense, R-Telecom, P-Finance

Verify which of the options satisfies the x=2 when y=-1.
Then the Answer is x = - (y - |y|)
Question 9

Most experts feel that in spite of possessing all the technical skills required to be a batsman of the highest order, he is unlikely to be so due to lack of requisite temperament. He was guilty of throwing away his wicket several times after working hard to lay a strong foundation.

(ii) and (iii)
C
(i), (ii) and (iii)
D
(ii) only
       Aptitude       Verbal
Question 9 Explanation: 
Statement (ii) and (iii) are True.
→ He is unlikely due to lack of requisite temperament ------- (ii) is True
→ He was guilty of throwing away his wicket several times ------- (iii) is True
Question 10

Alexander turned his attention towards India, since he had conquered Persia. Which one of the statements below is logically valid and can inferred from the above sentence?

A
Alexander would not have turned his attention towards India had he not conquered Persia

D
Since Alexander’s kingdom extended to Indian borders after the conquest of Persia, he was keen to move further
       Aptitude       Verbal
Question 10 Explanation: 
Let X be "Alexander turned his attention towards India"
Y be " he had conquered Persia"
Like that
∼X be "Alexander would not have turned his attention towards India"
then
∼Y be "he had not conquered Persis"
Answer is option A.
Question 11

In a room there are only two types of people, namely Type 1 and Type 2. Type 1 people always tell the truth and Type 2 people always lie. You give a fair coin to a person in that room, without knowing which type he is from and tell him to toss it and hide the result from you till you ask for it. Upon asking, the person replies the following:

“The result of the toss is head if and only if I am telling the truth.”

Which of the following options is correct?

A
The result is head
B
The result is tail
C
If the person is of Type 2, then the result is tail
D
If the person is of Type 1, then the result is tail
       Engineering-Mathematics       Prepositional-Logic
Question 11 Explanation: 
We do not know the type of person from whom those words are coming from and so we can have two cases.
Case 1:
The person who speaks truth. This definitely implies that result of toss is Head.
Case 2:
The person who lies. In this the reality will be the negation of the statement.
The negation of (x⇔y) is exactly one of x or y holds. "The result of the toss is head if and only if I am telling the truth". So here two possibilities are there,
→ It is head and lie spoken.
→ It is not head and truth spoken.
Clearly, the second one cannot speaks the truth. So finally it is head.
Hence, option (A).
Question 12

Consider the relation X(P, Q, R, S, T, U) with the following set of functional dependencies

F = {
       {P, R} → {S,T},  
       {P, S, U} → {Q, R}
    }

Which of the following is the trivial functional dependency in F+ is closure of F?

A
{P,R}→{S,T}
B
{P,R}→{R,T}
C
{P,S}→{S}
D
{P,S,U}→{Q}

Question 12 Explanation: 
X→Y is trivial if Y⊆ X

Given a hash table T with 25 slots that stores 2000 elements, the load factor α for T is ___________.

A
80
B
70
C
60
D
