Question : Find the value of the given expression: $\frac{(4\frac{1}{3}+3\frac{1}{3}\times 1\frac{4}{5}\div 3\frac{3}{4}\times (1\frac{1}{2}+1\frac{1}{3}))}{(\frac{2}{3}\div \frac{5}{6}\times \frac{2}{3})}$
Option 1: $11 \frac{3}{8}$
Option 2: $10\frac{1}{8}$
Option 3: $14\frac{3}{8}$
Option 4: $16\frac{5}{8}$
Correct Answer: $16\frac{5}{8}$
Solution : Given, $\frac{(4\frac{1}{3}+3\frac{1}{3}\times 1\frac{4}{5}\div 3\frac{3}{4}\times (1\frac{1}{2}+1\frac{1}{3}))}{(\frac{2}{3}\div \frac{5}{6}\times \frac{2}{3})}$ Converting mixed fractions to improper fractions, = $\frac{(\frac{13}{3}+\frac{10}{3}\times \frac{9}{5}\div \frac{15}{4}\times (\frac{3}{2}+\frac{4}{3}))}{(\frac{2}{3}\div \frac{5}{6}\times \frac{2}{3})}$ = $\frac{(\frac{13}{3}+\frac{10}{3}\times \frac{36}{75}\times \frac{17}{6})}{(\frac{4}{5}\times \frac{2}{3})}$ = $\frac{(\frac{13}{3}+\frac{68}{15})}{(\frac{8}{15})}$ = $\frac{(\frac{133}{15})}{(\frac{8}{15})}$ = $\frac{133}{8}$ = $16\frac{5}{8}$ Hence, the correct answer is $16\frac{5}{8}$.
Question : A man buys a watch for Rs. 1,950 in cash and sells it for Rs. 2,200 at a credit of 1 year. If the rate of interest is 10% per annum, then how much profit or loss will he have?

Question : The value of $\frac{1}{(p-n)(n-q)}+\frac{1}{(n-q)(q-p)}+\frac{1}{(q-p)(p-n)}$ is:
Option 1: $1$
Option 2: $0$
Option 3: $p + q + n$
Option 4: $\frac{2n}{p+q}$
Correct Answer: $0$
Solution : Given: $\frac{1}{(p-n)(n-q)}+\frac{1}{(n-q)(q-p)}+\frac{1}{(q-p)(p-n)}$ = $\frac{q-p+p-n+n-q}{(p-n)(n-q)(q-p)}$ = $0$ Hence, the correct answer is 0.

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: According to the passage, which of the following is NOT a cause of the spread of false information on social media?
Option 1: Lack of education and critical thinking skills among social media users.
Option 2: Inability to discern between credible sources and fake news.
Option 3: Social media companies’ failure to regulate false information on their platforms.
Option 4: The desire of people to engage in controversial and sensational content.
Correct Answer: The desire of people to engage in controversial and sensational content.
Solution : The correct answer is the fourth option.
The passage primarily focuses on factors like the lack of education and critical thinking skills, the inability to discern credible sources, and the failure of social media companies
