Q1. There are two candidates P and Q in an election. During the campaign, 40% of the voters promised to vote for P, and rest for Q. However, on the day of election 15% of the voters went back on their promise to vote for P and instead voted for Q. 25% of the voters went back on their promise to vote for Q and instead voted for P. Suppose, P lost by 2 votes, then what was the total number of voters?
Answer : Option A
Explaination / Solution:
Q2. Choose the most appropriate word from the options given below to complete the following sentence:
It was her view that the country's problems had been_________ by foreign technocrats, so that to invite them to come back would be counter-productive.
Answer : Option C
Explaination / Solution:
The clues in the question are ---foreign technocrats did something negatively to the problems – so it is counter-productive to invite them. All other options are non-negative. The best choice is exacerbated which means aggravated or worsened.
Q3. Choose the word from the options given below that is most nearly opposite in meaning to the given word:
Frequency
Answer : Option B
Explaination / Solution:
The best antonym here is rarity which means shortage or scarcity.
Q4. The horse has played a little known but very important role in the field of medicine. Horses were injected with toxins of diseases until their blood built up immunities. Then a serum was made from their blood. Serums to fight with diphtheria and tetanus were developed this way.
It can be inferred from the passage that horses were
Answer : Option B
Explaination / Solution:
From the passage it cannot be inferred that horses are given immunity as in (A), since the aim is to develop medicine and in turn immunize humans. (B) is correct since it is given that horses develop immunity after some time. Refer “until their blood built up immunities”. Even (C) is invalid since medicine is not built till immunity is developed in the horses. (D) is incorrect since specific examples are cited to illustrate and this cannot capture the essence.
Q5.
An open loop system represented by the transfer function 
is
is
Answer : Option B
Explaination / Solution:
Open loop system stability is depends only on pole locations ⇒ system is stable
There is one zero on right half of s-plane so system is non – minimum phase
Q6. With K as a constant, the possible solution for the first order differential equation 
is
is
Answer : Option A
Explaination / Solution:
Q7. The fourier series expansion 
of the periodic
signal shown below will contain the following nonzero terms
of the periodic
signal shown below will contain the following nonzero terms
Answer : Option D
Explaination / Solution:
⇒ it satisfies the half wave symmetry, so that it contains only odd harmonics.
⇒ It satisfies the even symmetry. So bn = 0
Q8. A three-phase, salient pole synchronous motor is connected to an infinite bus. Ig is operated at no load a normal excitation. The field excitation of the motor is first reduced to zero and then increased in reverse direction gradually. Then the
armature current
Answer : Option B
Explaination / Solution:
No Explaination.
Q9. Consider the following statement
(i) The compensating coil of a low power factor wattmeter compensates the effect of the impedance of the current coil.
(ii) The compensating coil of a low power factor wattmeter compensates the effect 0of the impedance of the voltage coil circuit.
Answer : Option B
Explaination / Solution:
No Explaination.
Q10. A three-phase current source inverter used for the speed control of an induction
motor is to be realized using MOSFET switches as shown below. Switches S1 to S6 are identical switches.
The proper configuration for realizing switches S1 to S6 is
Answer : Option C
Explaination / Solution:
No Explaination.
