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%.
The plots below depict and compare the average monthly incomes (in Rs. ’000) of males and females in ten cities of India in the years 2005 and 2015. The ten cities, marked A-J in the records, are of different population sizes. For a fair comparison, to adjust for inflation, incomes for both the periods are scaled to 2025 prices. Each red dot represents the average monthly income of females in a particular city in a particular year, while each blue dot represents the average monthly income of males in a particular city in a particular year. The gender gap for a city, for a particular year, is defined as the absolute value of the average monthly income of males, minus the average monthly income of females, in that year.
