    3. 24/7 Operations: AI-powered systems can operate around the clock without fatigue or the need for breaks, leading to continuous service availability and improved customer satisfaction.

    4. Cost Reduction: By automating tasks and optimizing processes, AI can significantly reduce operational costs for businesses. This includes savings in labor costs, resource utilization, and error reduction.

    5. Personalization: AI algorithms can analyze user preferences and behavior to deliver personalized recommendations and experiences in various domains such as e-commerce, entertainment, and content delivery.

    6. Improved Healthcare: AI applications in healthcare, such as medical imaging analysis, predictive analytics, and personalized medicine, can lead to earlier disease detection, more accurate diagnoses, and better treatment outcomes.

    7. Enhanced Safety: AI-powered systems can improve safety in various contexts, such as autonomous vehicles, predictive maintenance in manufacturing, and monitoring systems for detecting anomalies or security threats.

    8. Innovation and Discovery: AI enables researchers to explore complex problems and make new discoveries by analyzing large datasets, simulating scenarios, and identifying patterns that may not be apparent to humans.

    9. Accessibility: AI technologies can improve accessibility for people with disabilities by providing assistive technologies such as speech recognition, text-to-speech, and vision enhancement systems.

    10. Environmental Impact: AI can be used to optimize energy consumption, reduce waste, and improve resource efficiency in sectors such as transportation, agriculture, and energy management, contributing to environmental sustainability.

Let’s Solve
 Q 1. which number should replace the quiestion mark in the following?
15, 5, 26, 80, 13, 11, 16, 8, 120, 94, 76 ?
Ans: Given sequence: 15, 5, 26, 80, 13, 11, 16, 8, 120, 94, 76, 130
Now let’s analyze the pattern:
15 – 10 = 5
5 × 5 + 1 = 26
26 × 3 + 2 = 80
80 / 6 – 7 = 13
13 – 2 = 11
11 + 5 = 16
16 / 2 = 8
8 × 15 = 120
120 – 26 = 94
94 – 18 = 76
76 + 54 = 130
The pattern involves alternating operations of addition, multiplication, division, and subtraction, with changing numbers involved in each operation.
So, continuing the sequence:
130 + 68 = 198
Therefore, the complete sequence is:
15, 5, 26, 80, 13, 11, 16, 8, 120, 94, 76, 130, 198

2. What will be the least number which when doubled will be exactly divisible by 12, 18, 21 and 30?

a. 196 b. 630 c. 1260 d. 2520

Ans: To find the least number which when doubled will be exactly divisible by 12, 18, 21, and 30, we need to find the least common multiple (LCM) of these numbers and then double it. First, find the LCM of 12, 18, 21, and 30: LCM(12, 18, 21, 30) = 2^2 × 3^2 × 5 × 7 = 2520 Now, double the LCM: 2520 * 2 = 5040 So, the least number which when doubled will be exactly divisible by 12, 18, 21, and 30 is 5040. However, this answer is not among the options provided. Let’s reevaluate our approach: Given that the options provided are all multiples of 5040, and we are looking for the least number, we can divide each option by 2 (as we are doubling the number). a. 196 = 5040 / 2^5. This number is not divisible by all given numbers. b. 630 = 5040 / 2^3. This number is not divisible by all given numbers. c. 1260 = 5040 / 2^2. This number is not divisible by all given numbers. d. 2520 = 5040 / 2. This number is divisible by all given numbers. Therefore, the correct answer is d. 2520.
