Question : Comprehension: Read the given passage carefully and answer the questions that follow. The rise of social media has undoubtedly changed the way we communicate with one another. It has connected people from all over the world and provided a platform for voices that were once silenced. However, as with any form of communication, social media has its downsides. One of the most significant downsides is the spread of misinformation. With the rise of social media, anyone can become a content creator, which means that anyone can share information without fact-checking or considering the consequences. This has led to a proliferation of false information, from conspiracy theories to hoaxes, that can quickly spread and cause harm. One recent example of this is the COVID-19 pandemic. Social media has played a significant role in the spread of misinformation about the virus and the vaccines. False claims about the safety and effectiveness of the vaccines have caused many people to be hesitant or outright refuse to get vaccinated. This, in turn, has led to the prolongation of the pandemic and the loss of many lives. The spread of misinformation on social media is not a new phenomenon. In fact, it has been around for centuries. However, the speed and ease with which misinformation can spread on social media have made it a particularly pernicious problem in our modern world. Throughout history, misinformation has been used to sow discord and manipulate people. For example, during World War II, the Nazi regime used propaganda to spread false information about Jews, Roma, and other targeted groups in order to justify their persecution and ultimately their extermination. Similarly, during the Cold War, both the United States and the Soviet Union used propaganda to demonise one another and sway public opinion. The difference now is that social media has made it easier than ever to spread false information. A single post or tweet can reach millions of people within seconds, and it can be difficult to counteract the effects of that misinformation once it has spread. So, what can we do about it? The answer is not simple, but it starts with education. We need to teach people how to think critically, how to fact-check, and how to discern between credible sources and fake news. We also need to hold social media companies accountable for the content on their platforms and ensure that they are doing their part to combat the spread of misinformation. In short, the rise of social media has given us a powerful tool for communication, but we must use it wisely. We must be vigilant against the spread of misinformation and work together to ensure that the information we consume and share is accurate and reliable. Question: What is the author's opinion of social media in this passage?
Option 1: Social media has had a mostly positive impact on society, despite some drawbacks.
Option 2: Social media is responsible for the spread of false information, but its impact on society is otherwise neutral.
Option 3: Social media has changed the way we communicate, but it has also brought about significant negative consequences.
Option 4: Social media is a powerful tool for communication that has many benefits.
Correct Answer: Social media has changed the way we communicate, but it has also brought about significant negative consequences.
Solution : The correct answer is the third option.
While the passage acknowledges the positive aspects of social media, such as connecting people globally and providing a platform for silenced voices,
Question : The radius of a right circular cone is 3 cm and its height is 4 cm. The total surface area of a cone is:
Option 1: 48.4 cm2
Option 2: 64.4 cm2
Option 3: 96.4 cm2
Option 4: 75.4 cm2
Correct Answer: 75.4 cm2
Solution : The total surface area of a right circular cone of radius $r$ and slant height $l$ is $\pi r (r + l)$. Given: $r = 3 \, \text{cm}$ and $h = 4 \, \text{cm}$. $⇒l = \sqrt{r^2 + h^2}$ $⇒l = \sqrt{3^2 +

Question : Select the option that can be used as a one-word substitute for the given group of words. A decision on which one cannot go back
Option 1: Incorrigible
Option 2: Irrevocable
Option 3: Improbable
Option 4: Incredible

Solution : The correct choice is the second option.
Irrevocable means something that is final and cannot be changed, making it the correct one-word substitute for a decision on which one cannot go back.
The meanings of the other options are as follows:
Question : If $8 \cot \theta=6$, then the value of $\frac{\sin \theta+\cos \theta}{\sin \theta-\cos \theta}$ is:
Option 1: 12
Option 2: 7
Option 3: 2
Option 4: 5
Correct Answer: 7
Solution : $8 \cot \theta = 6$ $\therefore \cot \theta = \frac{6}{8}$ Now, $\frac{(\sin \theta+\cos \theta)}{(\sin \theta-\cos \theta)}$ Dividing numerator and denominator by $\sin \theta$ $=\frac{(1+\cot \theta )}{(1-\cot \theta)}$ $=\frac{1+ \frac{6}{8}}{1- \frac{6}{8}}$ $=\frac{\frac{14}{8}}{\frac{2}{8}}$ $=\frac{14}{2}$ $=7$ Hence, the correct answer is 7.
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at (1), (2), and (3) that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).

Option 1: (1)
Option 2: (2)
Option 3: (3)

Correct Answer: (4)
Solution : The correct choice is the fourth option.
The sentence correctly follows the sentence structure in the case of correlative conjunctions, as "scarcely is followed by....when" while maintaining the tense consistency.
Question : The following pie chart shows the monthly sales of laptops of five companies A, B, C, D, and E in a store.
If the store sold 2500 laptops in a month, then what is the difference between the number of laptops sold by Company A and that of Company C?
Option 1: 750
Option 2: 650
Option 3: 800
Option 4: 700
Correct Answer: 800
Solution : Number of laptops sold by the store in a month = 2500 Laptop sold by company A = 40% of 2500 = $\frac{2500\times{40}}{100}$ = 1000 Laptop sold by company C = 8% of 2500 = $\frac{2500\times{8}}{100}$ = 200 $\therefore$ The difference between the number of
Question : A and B started travelling towards each other at the same time, from places X to Y and Y to X, respectively. After crossing each other, A and B took 2.45 hours and 4.05 hours to reach Y and X, respectively. If the speed of B was 8.4 km/hr, then what was the speed (in km/hr) of A?
Option 1: 10.8
Option 2: 11.7
Option 3: 12.6
Option 4: 9.9
Correct Answer: 10.8
Solution : $\frac{\text{Speed of A}}{\text{Speed of B}}$ = $\sqrt{\frac{\text{Time Taken by B after crossing A }}{\text{ Time Taken by A after crossing B}}}$ According to the question $\frac{\text{Speed of A}}{8.4}=\sqrt{\frac{4.05}{2.45}}=\sqrt{\frac{81}{49}}$ $\therefore$ Speed of A $=\frac{9}{7} × 8.4= 10.8$ Hence, the correct answer is 10.8.
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 15, ?, 27, 39, 55, 75
Option 1: 19
Option 2: 20
Option 3: 21
Option 4: 18
Correct Answer: 19
Solution : Given: 15, ?, 27, 39, 55, 75
In the above-given series, add the multiples of 4 to the previous number to obtain the next number. 15 + 4 = 19; 19 + 8 = 27; 27 + 12 = 39; 39 + 16 = 55;
Question : Directions: In the following question a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series. 16, 61, 25, 52, 36, 63, 49, ?

Option 3: 46
Option 4: 72
Correct Answer: 94
Solution : Given: 16, 61, 25, 52, 36, 63, 49, ?
The numbers at odd places are the squares of consecutive numbers (starting from 4) and the even–placed numbers are the reverse of the previous numbers. (4)2 = 16; 16→61; (5)2 = 25; 25→52; (6)
