Question : As per Census 2011, which state of India has the lowest sex ratio, i.e., number of females per 1000 males?
Option 1: Uttarakhand
Option 2: Haryana
Option 3: Bihar
Option 4: Maharashtra
Correct Answer: Haryana
Solution : The correct option is Haryana.
The state of Haryana had the lowest sex ratio in India, according to the 2011 Census. The sex ratio is the number of females per 1000 males. The sex ratio in Haryana was 879 females per 1000 males. This ratio reflects a significant gender imbalance, with fewer females compared to males in the population.
Question : If $x(x-5)=-1$, then the value of $x^3\left(x^3-110\right)=$?
Option 1: 0
Option 2: –1
Option 3: 1
Option 4: 2
Correct Answer: –1
Solution : Given: $x(x-5)=-1$ ⇒ $x-5=-\frac{1}{x}$ ⇒ $x+\frac{1}{x}=5$ Cubing both sides, we get: ⇒ $(x+\frac{1}{x})^3=5^3$ ⇒ $x^3+\frac{1}{x^3}+3(x\times\frac{1}{x})(x+\frac{1}{x})=125$ ⇒ $x^3+\frac{1}{x^3}+3(x+\frac{1}{x})=125$ ⇒ $x^3+\frac{1}{x^3}+3\times5=125$ ⇒ $x^3+\frac{1}{x^3}=110$ ⇒ $x^3-110=-\frac{1}{x^3}$ $\therefore x^3(x^3-110)=-1$ Hence, the correct answer is –1.
Question : Directions: In a certain code language, HARMONIUM is written as LEVQSRMYQ. How is TOOLMAKER written in that code language?
Option 1: PZZLMLQVT
Option 2: XSSPQEOIV
Option 3: AZXCTVLKT
Option 4: AXXDFNOJQ
Correct Answer: XSSPQEOIV
Solution : Given: HARMONIUM is coded as LEVQSRMYQ.
Add 4 to the place value of each letter of HARMONIUM to obtain the required code – H + 4 = L; A + 4 = E; R + 4 = V; M + 4 = Q; O + 4 = S; N + 4 = R; I + 4 = M; U + 4 = Y; M + 4 = Q Thus, HARMONIUM is coded as LEVQSRMYQ. Similarly, follow the same pattern for TOOLMAKER – T + 4 = X; O + 4 = S; O + 4 = S; L + 4 = P; M + 4 = Q; A + 4 = E; K + 4 = O; E + 4 = I; R + 4 = V
So, TOOLMAKER is coded as XSSPQEOIV. Hence, the second option is correct.
Question : What is the number of valid votes cast in favour of a candidate in an election, if the candidate received 75% of the total valid votes, and 5% of the total votes were declared invalid, given that the total number of voters was 1,46,000?
Option 1: 1,06,650
Option 2: 1,10,250
Option 3: 1,04,025
Option 4: 1,08,850
Correct Answer: 1,04,025
Solution : The total number of votes is 1,46,000. Given that 5% of the votes were invalid, the number of invalid votes is 5% of 1,46,000, which is 0.05 × 1,46,000 = 7,300 votes Therefore, the total number of valid votes is 1,46,000 – 7,300 = 1,38,700 votes The candidate received 75% of the total valid votes, which is 75% of 1,38,700, or 0.75 × 1,38,700 = 1,04,025 votes Hence, the correct answer is 1,04,025.
Question : Which article of the Constitution of India deals with the appointment of ad-hoc judges?
Option 1: Article 126
Option 2: Article 127
Option 3: Article 128
Option 4: Article 125
Correct Answer: Article 127
Solution : The correct option is Article 127.
In the Indian Constitution, the appointment of ad hoc judges is covered by Article 127 for the Supreme Court and Article 224A for the High Courts. These articles outline the situations where such appointments can be made, the eligibility criteria for the chosen judges, and the duration of their tenure. In both cases, ad-hoc judges are appointed to maintain a quorum for vital proceedings when sufficient permanent judges are unavailable.
Question : Scurvy is caused by not having enough ________, resulting in general weakness, anaemia, gum disease and skin bleeding.
Option 1: cyanocobalamin
Option 2: ascorbic acid
Option 3: niacin
Option 4: thiamine
Correct Answer: ascorbic acid
Solution : The correct option is ascorbic acid.
Scurvy is caused by insufficient ascorbic acid, also known as vitamin C, in the diet. Ascorbic acid is essential for synthesising collagen, a protein crucial for maintaining the integrity of connective tissues. Without adequate vitamin C intake, collagen synthesis is impaired, leading to symptoms such as general weakness, anaemia, gum disease, and skin bleeding characteristic of scurvy.

Therefore, the correct answer would be: with another person in their presence rather than, say, by phone or letter.
Question : Comprehension:
Read the passage carefully and answer the question that follows.
Humans are social animals by nature. To prosper in life, we require the company of others, and the strength of our bonds has a significant influence on our mental health and happiness. Being socially linked to people may help you cope with stress, worry and depression, increase your self-esteem, bring comfort and joy, prevent loneliness, and even add years to your life. On the other hand, a lack of strong social relationships might put your mental and emotional health in danger. Many of us use social media sites like Facebook, Twitter, Snapchat, YouTube and Instagram to locate and communicate with one another in today's society. While each has its own set of advantages, it's vital to realise that social media will never be a substitute for genuine human interaction. In order to trigger the hormones that relieve stress and make you feel happier, healthier, and more optimistic, you must interact with individuals in person. Spending too much time on social media, ironically for a tool supposed to bring people closer together, can instead make you feel more lonely and isolated, and aggravate mental health issues like anxiety and depression. If you're spending too much time on social media and are experiencing emotions of unhappiness, discontent, irritation or loneliness, it's time to re-evaluate your online habits and establish a healthier balance.
Because social media is such a new technology, little study has been done to determine the long-term effects, good or ill, of its use. Multiple studies, however, have linked extensive social media use to an increased risk of melancholy, anxiety, loneliness, self-harm and even suicide ideation. The purpose of social media sites is to capture your interest, keep you online, and keep you checking your screen for updates. It's how businesses generate money. However, much like a gambling addiction or a nicotine, alcohol, or drug addiction, social media use may lead to psychological cravings. When you get a like, a share, or a positive reaction to a post, your brain releases dopamine, the same 'reward' chemical that you get after winning at a slot machine, eating chocolate, or smoking a cigarette, for example. The more you're rewarded, the more time you want to spend on social media, even if it has negative consequences in other areas of your life.

Question : In an election between 2 parties A and B, A gets 37% of total votes cast and thus lost by 338 votes. The total number of cast votes is (assume none of the votes was declared invalid):
Option 1: 1300
Option 2: 1500
Option 3: 1200
Option 4: 1800
Correct Answer: 1300
Solution : Let the total no. of votes cast be $x$ A gets 37% of the total votes then B gets = 100 – 37% = 63% votes Difference of votes of A and B = 63% – 37% = 26% According to the question, 26% of $x$ = 338 $⇒ \frac{26}{100} \times x = 338$ $⇒ 26x = 33800$ $⇒ x = \frac{33800}{26}$ = 1300 ∴ The total number of cast votes is 1300. Hence, the correct answer is 1300.
