Question : $x$ is a negative number such that $k+k^{-1}=-2$, then what is the value of $\frac{k^2+4 k-2}{k^2+k-5}$?
Option 1: 7
Option 2: 1
Option 3: –7
Option 4: –1
Solution : Given: $k+k^{-1}=-2$ ⇒ $k+\frac{1}{k}=-2$ ⇒ $k^2+1=-2k$ ⇒ $k^2+2k+1=0$ ⇒ $(k + 1)^2=0$ $\therefore k=-1$ Putting the value of $k$ in the given equation, $\frac{k^2+4 k-2}{k^2+k-5}$ $=\frac{(-1)^2+4 (-1)-2}{(-1)^2+(-1)-5}$ $=\frac{1-4-2}{1-1-5}$ $=\frac{-5}{-5}$ $=1$ Hence, the correct answer is 1.
Question : Directions: In the following question, out of the four alternatives, select the alternative that will improve the bracketed part of the sentence. In case no improvement is needed, select "No Improvement".
She thought that she would destroy it with her own hands (rather than allowing) it to be misused.
(1) rather than allow
(2) than rather allowing
(3) than rather allow
(4) No Improvement
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (1)
Solution : The sentence can be improved using the first option.
When we use "rather than" in a sentence, the form of the verb after "rather than" depends on the parallel structure of the sentence. Since "destroy" is used in the sentence, "allow" is the correct choice

Option 1: FQEUPS
Option 2: EQDUPS
Option 3: FQEVQT
Option 4: EQEVQT
Correct Answer: FQEVQT
Solution : Given: OXYGEN is written as QZAIGP and MIND is written as OKPF.
Two is added to the place value of each letter of OXYGEN, to obtain the required code — O + 2 = Q; X + 2 = Z; Y + 2 = A;

The meanings
Read the given passage and answer the questions that follow.
Although pollution of land, sea, and air has been well documented, the latest and the least recognised version is the swelling tide of noise which is engulfing urban as well as rural areas. This has long-term implications for the ecology, health and productivity of a fast-developing country like India.
Unlike other pollutants, noise lacks visibility, seldom registering on the consciousness, except as a trifling irritant to be dismissed at will and therefore less likely to be perceived as a threat. Available data indicates that noise does pose a threat to health and is known to have caused a number of complications. Declining productivity among workers in certain industries has been directly correlated with noise levels, particularly those under constant exposure to the menace.
The first-ever survey of the impact of noise on health, conducted by All India Institute of Medical Sciences (AlIMS), has established that noise not only impairs the physical and psychological functioning of the human organism but also causes nausea, vomiting, pain, hypertension and a lot of other complications, including cardio-vascular complaints. A study by the Post Graduate School of Basic Medical Sciences, Chennai, confirms such conclusions. In 50 per cent of industries, it was found that workmen exposed to higher intensities of noise in occupational capacities were often irritated, short-tempered, impatient and more likely to resort to agitation and disrupt production. This was true of units in heavy industrial pockets in and around the four metropolitan centres.
Recreational noise, another ugly facet, is becoming more widespread in cities and towns. Loudspeakers are turned at full volume during marriages, festivals, jaguars, and musical programmes, particularly at night, without the least consideration for others. Even at 50 dB, sound can awaken a person from a deep slumber. As experiments have shown, loudspeakers with output from 60 to 80 dB cause the pupils of a slumbering person to dilate, with increasing intake of oxygen, resulting in palpitation. The effect is more pronounced in narrow lanes. TV sets are played at full volume at prime time, invariably disturbing neighbours. Noise-making seems to have become the latest status symbol, be it an election campaign, slogan shouting, or advertising ownership of a TV set.
In what way does noise become a status symbol?
Option 1: Exposing workmen to high intensity sounds
Option 2: Showing off the loud volume of one's TV
Option 3: Awakening people from deep sleep
Option 4: Conducting late night musical shows
Correct Answer: Showing off the loud volume of one's TV
Solution : The correct choice is the second option.
The passage mentions in the last line that noise-making has become a symbol of status, particularly highlighted by instances like playing TV sets at full volume during prime time and disturbing
