The goal is to find the lowest percentage of students likely to vote. Let's examine each situation:
1. Both campaign on issues:
The voting percentage is calculated as: 20 × (Amiya's campaign level + Ramya's campaign level).
The lowest campaign level for both is 1 (staid). So, the voting percentage is: 20 × (1 + 1) = 40%.
2. Amiya attacks, Ramya campaigns on issues:
Starting from the base 40% (calculated above), adjustments are made. 10% of Amiya's potential votes (half of 40%) shift to Ramya, and another 10% of Amiya's potential votes become disengaged. Therefore, the final voting percentage is 40% - (0.1 × 20%) = 38%.
3. Ramya attacks, Amiya campaigns on issues:
This scenario is the reverse of the previous one. Starting with 40%, adjustments are: 20% of Ramya's potential votes (half of 40%) go to Amiya, and 5% of Ramya's potential votes become disengaged. Thus, the voting percentage is 40% - (0.05 × 20%) = 39%.
4. Both attack:
Starting with 40% potential votes, 10% of students become disengaged and do not vote. The voting percentage is calculated as: 40% × (1 - 0.1) = 36%.
Comparing all scenarios, the minimum percentage of students who will vote is 36%.
To find the minimum percentage of votes Ramya is guaranteed when attacking Amiya, we examine a specific scenario: Ramya attacks, and Amiya focuses on issues. The calculation proceeds as follows:
1. Initial State: Both candidates campaign by focusing on issues at a vigorous level (Level 2).
a. Combined campaign level: \(2+2=4\)
b. Total voting percentage: \(20 \times 4 = 80\%\)
c. Ramya's initial vote share: \(\frac{2}{4} \times 80\% = 40\%\)
2. Ramya Switches Strategy: Ramya attacks Amiya, while Amiya continues to focus on issues.
a. Votes lost by Ramya to Amiya: 20% of Ramya's initial votes (40%) switch to Amiya, equating to \(0.2 \times 40\% = 8\%\).
b. Voters lost by Ramya to abstention: 5% of Ramya's initial votes (40%) will not vote, equating to \(0.05 \times 40\% = 2\%\).
c. Ramya's adjusted vote percentage: \(40\% - 8\% - 2\% = 30\%\)
3. Worst-Case Scenario: Both candidates attack each other.
a. Voting percentage with mutual attacks: \(90\% \times 80 = 72\%\)
b. Ramya's vote share in this scenario: \(\frac{40\%}{80\%} \times 72\% = 36\%\)
Considering all scenarios, Ramya's vote percentages are 30%, 15%, and 36%. Therefore, the minimum guaranteed percentage for Ramya when she attacks is 15%.
To find the largest possible voting margin for a candidate's win, let's examine the outcomes based on the described campaign strategies:
Let's break down the scenarios to determine the maximum possible margin:
The maximum possible margin is achieved when Ramya attacks and Amiya focuses on issues (Amiya vigorous, Ramya staid), resulting in a 29% margin for Amiya.
Therefore, the maximum voting margin is 29%.
A pie chart shows the allocation of a 260 lakh annual budget among 5 departments. If the Health department gets 18% and Education gets 24%, how much more does Education get than Health? 
A pie chart shows the distribution of students across 5 faculties in a university. If 20% are in Arts, 25% in Science, 15% in Law, 30% in Engineering, and the rest in Commerce, what is the angle (in degrees) for Commerce?
A bar graph shows the number of students in 5 departments of a college. If the average number of students is 240 and the number of students in the Science department is 320, how many students are there in total in the other four departments?
