Given the problem, we need to determine the minimum percentage of students who will vote in the election. Let's analyze each scenario:
1. Both run campaigns focusing on issues:
The voting percentage is calculated as follows: 20 × (Level of Amiya + Level of Ramya)
.
Minimum campaign level for both = 1 (staid), thus, 20 × (1+1) = 40%
.
2. Amiya attacks, Ramya focuses on issues:
Starting from a staid focus level 1 each, we get 40% (as calculated above). Adjustments: 10% of Amiya's potential votes (1/2 of 40%) switch to Ramya, and another 10% of Amiya's potential votes don't vote. Therefore, final voting = 40% - (0.1 × 20%) = 38%.
3. Ramya attacks, Amiya focuses on issues:
This is symmetric to the previous scenario, so starting with 40%, adjustments yield: 20% of Ramya's potential votes switch to Amiya (1/2 of 40%), and another 5% of Ramya's potential votes don't vote. Thus, voting = 40% - (0.05 × 20%) = 39%.
4. Both attack:
Starting with potential votes of 40%, 10% of students don't vote at all as they are otherwise disinterested. Voting percentage: 40% × (1 - 0.1) = 36%
.
Given the scenarios, the minimum percentage of students who will vote is 36%.
To determine the minimum percentage of votes Ramya is guaranteed to get when she runs a campaign attacking Amiya, we'll consider the scenario when Ramya attacks and Amiya focuses on issues. Here's how the calculation works:
1. Assume both candidates initially run campaigns focusing on issues. If both run vigorous campaigns (Level 2):
a. Total campaign level = \(2+2=4\)
b. Voting percentage = \(20 \times 4 = 80\%\)
c. Ramya's share of initial votes = \(\frac{2}{4} \times 80\% = 40\%\)
2. Ramya changes her strategy to attack Amiya while Amiya focuses on issues:
a. 20% of Ramya's initial votes (40%) switch to Amiya = \(0.2 \times 40\% = 8\%\)
b. 5% of Ramya's initial votes will not vote at all = \(0.05 \times 40\% = 2\%\)
c. Ramya's new vote percentage = \(40\% - 8\% - 2\% = 30\%\)
3. Consider both candidates attack to find the worst-case scenario for Ramya:
a. Voting percentage if both attack = \(90\% \times 80 = 72\%\)
b. Ramya's share = \(\frac{40\%}{80\%} \times 72\% = 36\%\)
Combining worst cases, Ramya gets: 30%, 15%, and 36% respectively in scenarios. Thus, the minimum guaranteed percentage when Ramya attacks is 15%.
To determine the maximum possible voting margin with which one of the candidates can win, we need to analyze the voting scenarios based on the campaign strategies described:
Let's determine the maximum margin with a detailed breakdown of scenarios:
To get the maximum possible margin: When Ramya attacks, Amiya issues (vigorous, staid), Amiya gains 29% margin.
Thus, the maximum voting margin is 29%.
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?
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?
