Question : Directions: In the given question, a sentence is given with a blank to be filled in with an appropriate word. Four alternatives are suggested for each question. Choose the correct alternative out of the four alternatives.
Those sort of people (1) / are always nice (2) / to you on your face. (3) / No Error (4)
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (1)
Solution : The correct choice is the first option.
"Those sort of people" should be replaced with "those sorts of people", as plural pronouns must be used for plural nouns per the subject-verb agreement.
Therefore, the correct sentence is: Those sorts of people are always nice
Question : Which of the following properties of sound is affected by a change in air temperature?
Option 1: Frequency
Option 2: Intensity
Option 3: Amplitude
Option 4: Wavelength
Correct Answer: Wavelength
Solution : The correct option is Frequency.
As temperature changes will have an impact on velocity, they will also have an impact on frequency because frequency and sound velocity are inversely related. Temperature fluctuations in the air have an impact on sound propagation in that medium.

Question : Simplify the given expression $\frac{3\left(\sin ^4 z-\cos ^4 z+1\right)}{\sin ^2 z}$
Option 1: 9
Option 2: 2
Option 3: 4
Option 4: 6
Correct Answer: 6
Solution : Given, $\frac{3\left(\sin ^4 z-\cos ^4 z+1\right)}{\sin ^2 z}$ Using $a^2-b^2=(a-b)(a+b)$ = $\frac{3((\sin^2z-\cos^2z)(\sin^2z+\cos^2z)+1)}{\sin^2z}$ We know, $\sin^2\theta + \cos^2\theta = 1$ = $\frac{3((\sin^2z-\cos^2z)(1)+1)}{\sin^2z}$ = $\frac{3(\sin^2z+(1-\cos^2z))}{\sin^2z}$ = $\frac{3(\sin^2z+\sin^2z)}{\sin^2z}$ = $\frac{3(2\sin^2z)}{\sin^2z}$ = 6 Hence, the correct answer is 6.
Question : Comprehension:
In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.
Unemployment arises from a variety of_____ (1). One which is always recurring and the effects of which we have had a recent example is the disorganisation of the industry resulting from a long war, this is a serious______ (2) admitting of no easy ________(3) at the best of times. Again there is unemployment which followed a marked diminution in the______ (4) of any raw product, such as cotton; fewer hands are required in the mills and the factories. We may call this the cause of bad harvests. Similar, but more serious is the effect of changes in industry due to the invention of machinery which does more work and requires________ (5) hands. Yet another cause is strike or lockout and this is more to be deplored because such a stoppage is due to a very trivial matter, perhaps the men are working half an hour longer than what their Union permits.
Select the most appropriate option to fill in the blank number 3.
Option 1: key
Option 2: clue
Option 3: answer
Option 4: solution
Correct Answer: solution
Solution : The correct choice is the fourth option.
In the context of the sentence, the phrase "admitting of no easy" indicates a need for a term that signifies a resolution or answer. Among the options, solution is the most fitting word, as it refers to a
Question : The area of a circle whose radius is the diagonal of a square whose area is $4\;\mathrm{cm^2}$ is:
Option 1: $16\pi\;\mathrm{cm^2}$
Option 2: $4\pi\;\mathrm{cm^2}$
Option 3: $6\pi\;\mathrm{cm^2}$
Option 4: $8\pi\;\mathrm{cm^2}$
Correct Answer: $8\pi\;\mathrm{cm^2}$
Solution : The area of a square $= s^2$, (where $s$ is the side length of the square.) Given that the area of the square $=4\;\mathrm{cm^2}$ The side length of the square $=\sqrt{4} = 2\;\mathrm{cm}$ $\therefore$ The diagonal of a square $ = s\sqrt{2}=2\sqrt{2}\;\mathrm{cm}$ This diagonal is
