Polio vaccination is crucial for protecting children from the devastating effects of poliomyelitis, a highly contagious viral disease that can lead to permanent paralysis or even death. Children are particularly vulnerable to this disease, which spreads through contaminated water and food. Vaccination is the most effective way to prevent polio, as it builds immunity and stops the virus from spreading. Global efforts to eradicate polio have already made significant progress, and widespread vaccination campaigns have brought us closer to a polio-free world. By ensuring every child receives the polio vaccine, parents contribute to the larger goal of safeguarding entire communities and breaking the cycle of transmission. Early vaccination not only protects individual children but also helps achieve public health milestones, preventing the resurgence of a disease that has caused immense suffering in the past. Together, we can make a lasting impact and protect future generations.

Beyond physical health, walking contributes to mental well-being by relieving stress, improving mood, and boosting energy levels. This low-impact exercise is suitable for people of all ages and fitness levels, providing an accessible way to stay active without requiring expensive equipment or gym memberships. Additionally, walking outdoors allows individuals to connect with nature, which can be refreshing and inspiring. Whether it’s a brisk walk in the morning or a leisurely stroll in the evening, incorporating walking into daily routines promotes a healthier and happier lifestyle while fostering a sense of balance and harmony.

AIOU 247 Mathematics-I Solved Assignment 2 Spring 2025


AIOU 247 Assignment 2


Q1.(a). Find 3 A.Ms between √3 and 9√3(10 Marks)


Arithmetic Means between √3 and 9√3

We want three arithmetic means inserted between the two terms so the full sequence has five terms.

a₁ = √3, a₅ = 9√3

For an arithmetic sequence with five terms the common difference d satisfies

a₅ = a₁ + 4d

Substitute the values and solve for d

9√3 = √3 + 4d → d = 2√3

Now compute the three arithmetic means

• a₂ = a₁ + d = 3√3
• a₃ = a₁ + 2d = 5√3
• a₄ = a₁ + 3d = 7√3

Answer: 3√3, 5√3, 7√3


Q1.(b). The positive G.M between two numbers is 9 and the A.M between them is 15. Find the numbers.(10 Marks)


Finding the Numbers from A.M and G.M

The positive geometric mean (G.M) between two numbers a and b is 9. This gives:

√(ab) = 9 → ab = 81

The arithmetic mean (A.M) between them is 15. This gives:

(a + b) / 2 = 15 → a + b = 30

Step 1: The equations are:

a + b = 30, ab = 81

Step 2: Form quadratic equation:

x² - 30x + 81 = 0

Step 3: Solve:

x = (30 ± √(900 - 324)) / 2 = (30 ± 24) / 2

x = 27 or x = 3

Answer: The two numbers are 27 and 3

1. Is social media doing more harm than good to society?

Social media has become an integral part of modern life, connecting people worldwide and transforming communication. While its advantages are undeniable, its drawbacks raise important concerns about the harm it might be causing to society, especially in the context of mental health, relationships, and information integrity.

On the positive side, social media is an unmatched tool for global connectivity. It allows users to interact with friends, family, and colleagues across the globe in real time, fostering stronger relationships. Moreover, social media platforms have become spaces for creativity and self-expression, where people can showcase talents, share ideas, and engage in meaningful discussions. For businesses, social media provides unparalleled opportunities to reach and engage with customers, drive sales, and build brand identity. Additionally, social media plays a significant role in raising awareness about critical issues and promoting social movements, as seen in initiatives advocating for racial equality, environmental conservation, and gender rights.

Despite these benefits, social media's adverse effects can cast a shadow over its potential. One major issue is its detrimental impact on mental health, particularly among younger audiences. Constant exposure to idealized lifestyles, filtered images, and curated content creates unrealistic standards that lead to feelings of inadequacy, anxiety, and depression. Users often fall into the trap of comparing their lives to the seemingly perfect lives portrayed on these platforms, which can erode self-esteem and happiness.

Another pressing concern is the prevalence of misinformation and fake news. Social media platforms have struggled to combat the rapid spread of false narratives that can influence public opinion and decision-making. This challenge is compounded by algorithms that favor sensational and divisive content, creating echo chambers that reinforce biases and polarize society.

Social media also contributes to the erosion of genuine relationships. Its addictive nature encourages excessive screen time, reducing opportunities for face-to-face interactions and deepening the gap between individuals. The rise of cyberbullying and trolling further exacerbates the harmful impact on interpersonal dynamics, leaving many users vulnerable and disconnected.

Additionally, concerns about privacy and data security remain paramount. Social media platforms collect and analyze vast amounts of user data, often without clear consent, raising ethical questions about surveillance and exploitation.

The addictive design of social media platforms prioritizes engagement over well-being, making it easy for users to spend hours scrolling through feeds without realizing the toll it takes on their productivity and mental health. This culture of instant gratification contributes to a decline in attention spans, critical thinking, and overall well-being.

In conclusion, while social media offers remarkable benefits by connecting people, promoting creativity, and raising awareness about global issues, its negative consequences are significant and must not be overlooked. From mental health challenges and misinformation to addictive behaviors and privacy concerns, these drawbacks indicate that social media may be doing more harm than good. To address these issues, individuals must use social media mindfully, tech companies must implement responsible practices, and governments must enforce policies that prioritize user well-being over corporate profits. Only through collective efforts can society mitigate the harm caused by social media and foster a healthier, more constructive digital environment.


2. Should students have access to their phones during school hours?

The question of whether students should have access to their phones during school hours sparks a vibrant debate, encompassing issues of practicality, responsibility, and the balance between technology use and educational priorities. While smartphones are indispensable tools in modern society, their role in the school environment demands careful consideration.

On one side of the argument, granting students access to their phones during school hours offers undeniable benefits. Smartphones can be valuable for educational purposes, providing access to online resources, digital books, and learning apps. For example, students can quickly look up information, collaborate on assignments, and even participate in interactive learning activities. Moreover, phones can act as safety tools, enabling students to stay in touch with parents during emergencies or schedule changes. By learning to use their phones responsibly, students develop critical skills in managing technology, which is essential in today's world.

However, allowing phones during school hours also comes with risks that can significantly hinder the educational experience. Distractions are the primary concern, as social media, games, and notifications can divert attention away from lessons and diminish academic focus. The presence of phones may also encourage cyberbullying or inappropriate usage, leading to potential psychological harm. Additionally, excessive screen time can negatively impact students' ability to engage in face-to-face interactions, which are crucial for social development.

The availability of phones may exacerbate inequalities among students. Not all families can afford advanced smartphones or data plans, and this disparity can create social divisions within the classroom. Schools must ensure that technology access does not become a source of exclusion or competition.

To strike a balance, schools can adopt regulated policies that allow phone usage in controlled settings. For instance, phones could be permitted during specific periods, such as breaks or supervised activities, while being restricted during lessons to minimize distractions. Educators can also teach students about responsible digital habits, emphasizing the importance of using technology as a tool rather than a source of entertainment.

In conclusion, while smartphones can enhance learning and provide safety benefits, their potential to disrupt education and social dynamics cannot be overlooked. Schools must implement balanced policies that prioritize academic excellence and foster a supportive environment. By guiding students toward responsible phone use, schools can prepare them for a technology-driven future while preserving the sanctity of the classroom.

To tell you a bit about myself, I’ve always had a deep love for creative and active pursuits. One of my favorite hobbies is painting, where I enjoy experimenting with colors and bringing ideas to life on canvas—it’s my go-to way of expressing myself and unwinding. I’m also a huge fan of hiking and exploring nature; nothing beats the peace and perspective that come with being outdoors. On top of that, I dabble in cooking, and I love trying out recipes from around the world—it’s such a fun way to bond with people over food and culture.

As for why I joined this club, I’m truly excited about the chance to be part of something bigger. I see this as an opportunity to connect with like-minded people and build meaningful relationships. I’m also eager to collaborate on projects that can make a positive impact on both the club and the wider community. Whether it’s brainstorming ideas, organizing events, or simply lending a hand wherever needed, I’m ready to get involved.

On a personal level, I hope to learn from all of you and develop new skills along the way. Stepping outside my comfort zone and trying things I’ve never done before is something I always look forward to, and I believe this club provides the perfect space for that.

Thank you for welcoming me, and I can’t wait to contribute my energy and enthusiasm to this group. If you ever want to chat about art, plan a hike, or exchange recipes, I’m all ears. Here’s to an incredible journey together!

Time: 03 Hours

Semester: Spring 2022

Total Marks: 100

Pass Marks: 50


Question 1 (a) - A patient in a hospital is required to have at least 84 units of drug A and 120 units of drug B each day (assume that an over dosage of either drug is harmless). Each gram of substance M contains 10 units of drug A and 8 units of drug B, and each gram of substance N contains 2 units of drug A and 4 units of drug B. How many grams of substances M and N can be mixed to meet the minimum daily requirements?

Step-by-Step Solution

  1. Define the variables:
    • x: grams of substance M
    • y: grams of substance N
  2. Set up inequalities:
    • 10x + 2y ≥ 84
    • 8x + 4y ≥ 120
  3. Simplify inequalities:
    • 5x + y ≥ 42
    • 2x + y ≥ 30
  4. Solve for x:
    • Subtract inequalities: 5x + y - (2x + y) ≥ 42 - 30
    • Result: 3x ≥ 12
    • Divide by 3: x ≥ 4
  5. Solve for y:
    • Substitute x = 4 into 2x + y ≥ 30
    • Result: 2(4) + y ≥ 30
    • Simplify: 8 + y ≥ 30
    • y ≥ 22

To meet the minimum daily requirements, mix 4 grams of substance M and 22 grams of substance N.


Question 1 (b) - Find the following:

  1. What is y-intercept and slope of the equation 5x + 2y = 10?
  2. Determine the equation of a straight line whose y-intercept is-3 and slope 4
  3. Find the slope intercept form of the equation that passes through (-8, -4) and perpendicular to the line 8x - 2y = 0
  4. Determine the equation of a straight line which has a slope of -5 and x y intercept of(0,15)

Solution: Ushr is applicable at the rate of 10% for crops irrigated by natural resources. Ushr = (10 / 100) × Rs. 9,30,000 = Rs. 93,000 (b) Calculate Zakat on gold amounting to Rs. 13,50,000. Solution: Zakat is applicable at the rate of 2.5% on the total value of gold. Zakat = (2.5 / 100) × Rs. 13,50,000 = Rs. 33,750 Q2 (10 Marks) (a) If the stay of 12 men for 7 days in a hotel costs Rs. 20,500, find the cost for the stay of 10 men for 8 days. Solution: Cost is proportional to the number of men and the number of days. Cost per man per day = Rs. 20,500 ÷ (12 × 7) = Rs. 244.05 Cost for 10 men for 8 days = Rs. 244.05 × 10 × 8 = Rs. 19,524 (b) Two angles in a triangle are 45° and 75°. Find the ratio of the third angle to the sum of the first two angles. Solution: Third angle = 180° − (45° + 75°) = 60° Sum of first two angles = 45° + 75° = 120° Ratio = Third angle : Sum of first two angles = 60 : 120 = 1 : 2 Q3 (10 Marks) (a) The marked price of a wall clock is Rs. 900. The shopkeeper offers a discount of 5% and still gains 10%. Find the price at which the shopkeeper purchased it. Solution: Selling price after 5% discount = 95% of Rs. 900 = Rs. 855 Cost price = Selling price ÷ (1 + Gain%) = Rs. 855 ÷ 1.1 = Rs. 777.27 (b) Divide Rs. 18,400 among three friends such that the ratio of their parts is 3:6:8. Solution: Total parts = 3 + 6 + 8 = 17 Friend 1's share = (3 / 17) × Rs. 18,400 = Rs. 3,247.06 Friend 2's share = (6 / 17) × Rs. 18,400 = Rs. 6,494.12 Friend 3's share = (8 / 17) × Rs. 18,400 = Rs. 8,658.82 Q4 (10 Marks) (a) At what annual rate of profit would a sum of Rs. 780 increase to Rs. 1,340 in 2 years 3 months? Solution: Profit = Rs. 1,340 − Rs. 780 = Rs. 560 Time = 2 years 3 months = 2.25 years Rate = (Profit ÷ Principal × 100) ÷ Time = (Rs. 560 ÷ Rs. 780 × 100) ÷ 2.25 = 32.02% (b) Find the compound profit on Rs. 3,000 for 2 years at 4%. Solution: Use the compound interest formula: CI = Principal × [(1 + Rate / 100)^Time − 1] CI = Rs. 3,000 × [(1 + 4 / 100)^2 − 1] CI = Rs. 3,000 × (1.0816 − 1) = Rs. 244.80 Q5 (10 Marks) (a) The price of a motorcycle is Rs. 4,000. If 9% sales tax is charged, calculate the amount of sales tax on 25 such motorcycles. Solution: Sales tax per motorcycle = (9 / 100) × Rs. 4,000 = Rs. 360 Sales tax on 25 motorcycles = Rs. 360 × 25 = Rs. 9,000 (b) If gross pay of a person is Rs. 6,50,000, calculate his net take-home salary after deductions. Solution: Total deductions = Rs. 380 (income tax) + Rs. 700 (benevolent fund) + Rs. 2,100 (G.P. fund) + Rs. 250 (group insurance) = Rs. 3,430 Net salary = Gross pay − Total deductions = Rs. 6,50,000 − Rs. 3,430 = Rs. 6,46,570
