10 Aptitude Questions with Solutions

Question 1: Percentage

If the price of JioFiber plan increases by 20% and then decreases by 20%, what is the net percentage change?

Solution: Let original price = ₹100 After 20% increase = ₹120 After 20% decrease = ₹120 × 0.80 = ₹96 Net change = (100 - 96)/100 × 100 = 4% decrease

Question 2: Time and Work

12 engineers can complete a network installation in 15 days. How many engineers are needed to complete the same work in 10 days?

Solution: Total work = 12 × 15 = 180 engineer-days Engineers needed = 180/10 = 18 engineers

Question 3: Profit and Loss

A JioPhone is sold at a 15% profit. If it was bought for ₹1,200, what is the selling price?

Solution: Selling Price = Cost Price × (1 + Profit%) SP = 1200 × 1.15 = ₹1,380

Question 4: Speed and Distance

A network packet travels 1,200 km in 4 hours. What is its average speed in m/s?

Solution: Speed = 1200/4 = 300 km/h = 300 × (1000/3600) = 83.33 m/s

Question 5: Number Series

Find the next number: 2, 6, 12, 20, 30, ?

Solution: Pattern: n(n+1) 1×2=2, 2×3=6, 3×4=12, 4×5=20, 5×6=30, 6×7=42

Question 6: Ratio and Proportion

The ratio of 4G to 5G towers in a city is 3:2. If there are 450 4G towers, how many 5G towers are there?

Solution: 3 parts = 450, so 1 part = 150 5G towers = 2 × 150 = 300 towers

Question 7: Simple Interest

An investment of ₹50,000 yields ₹7,500 interest in 3 years. What is the rate of interest?

Solution: SI = PRT/100 7500 = 50000 × R × 3/100 R = (7500 × 100)/(50000 × 3) = 5%

Question 8: Probability

What is the probability of getting at least one head when two coins are tossed?

Solution: P(at least one head) = 1 - P(no heads) = 1 - (1/4) = 3/4

Question 9: Average

The average of 5 numbers is 24. If one number is excluded, the average becomes 22. What is the excluded number?

Solution: Sum of 5 numbers = 5 × 24 = 120 Sum of 4 numbers = 4 × 22 = 88 Excluded number = 120 - 88 = 32

Question 10: Data Interpretation

If Jio adds 2 million subscribers monthly, how many subscribers will it have after 1 year from 450 million?

Solution: Annual addition = 2 × 12 = 24 million Total after 1 year = 450 + 24 = 474 million

10 Domain-Specific Questions with Answers

Question 1: Telecommunications

Q: What is the frequency band used by Jio for 5G services in India? A: Jio uses the 700 MHz, 3500 MHz (n78), and 26 GHz (n258) bands for 5G services in India.

Question 2: Networking

Q: Explain the difference between 4G LTE and 5G NR. A: 5G NR offers lower latency (1ms vs 30-50ms), higher speeds (up to 20 Gbps vs 1 Gbps), massive MIMO, network slicing, and better spectral efficiency compared to 4G LTE.

Question 3: Computer Science

Q: What is the OSI model and how many layers does it have? A: The OSI (Open Systems Interconnection) model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

Question 4: Database

Q: What is the difference between SQL and NoSQL databases? Which does Jio use? A: SQL databases are relational with structured schema; NoSQL is non-relational, schema-less, and horizontally scalable. Jio uses both - SQL for transactional data and NoSQL (like Cassandra) for big data analytics.

Question 5: Programming

Q: Write a program to find the factorial of a number. A:

def factorial(n):
    if n == 0 or n == 1:
        return 1
    return n * factorial(n-1)

Question 6: Data Structures

Q: Explain the difference between Stack and Queue. A: Stack follows LIFO (Last In First Out) - elements added/removed from top. Queue follows FIFO (First In First Out) - elements added at rear, removed from front.

Question 7: Operating Systems

Q: What is the difference between process and thread? A: A process is an independent program with its own memory space. Threads are lightweight units within a process sharing the same memory space but executing independently.

Question 8: Cloud Computing

Q: What is virtualization and why is it important for telecom operators? A: Virtualization creates virtual versions of hardware resources, enabling efficient resource utilization, scalability, and cost reduction. For telecom, it enables NFV (Network Functions Virtualization).

Question 9: Data Analytics

Q: What is Big Data and what are the 3Vs? A: Big Data refers to extremely large datasets. The 3Vs are: Volume (amount of data), Velocity (speed of data generation), and Variety (different types of data).

Question 10: Cybersecurity

Q: What is a DDoS attack and how can it be prevented? A: Distributed Denial of Service attack floods a network with traffic to make it unavailable. Prevention includes traffic filtering, rate limiting, CDN usage, and DDoS protection services.
