What is the minimum percentage of students who will vote in the election?
Video Explanation

If both of them run staid campaigns attacking the other, then what percentage of students will vote in the
election?
Video Explanation

Two students, Amiya and Ramya are the only candidates in an election for the position of class representative.
Students will vote based on the intensity level of Amiya’s and Ramya’s campaigns and the type of campaigns
they run. Each campaign is said to have a level of 1 if it is a staid campaign and a level of 2 if it is a vigorous
campaign. Campaigns can be of two types, they can either focus on issues, or on attacking the other candidate.
If Amiya and Ramya both run campaigns focusing on issues, then
• The percentage of students voting in the election will be 20 times the sum of the levels of campaigning of the
two students. For example, if Amiya and Ramya both run vigorous campaigns, then 20 × (2+2)%, that is, 80% of
the students will vote in the election.
• Among voting students, the percentage of votes for each candidate will be proportional to the levels of their
campaigns. For example, if Amiya runs a staid (i.e., level 1) campaign while Ramya runs a vigorous (i.e., level 2)
campaign, then Amiya will receive 1/3 of the votes cast, and Ramya will receive the other 2/3. The abovementioned percentages change as follows if at least one of them runs a campaign attacking their opponent.
• If Amiya runs a campaign attacking Ramya and Ramya runs a campaign focusing on issues, then 10% of the
students who would have otherwise voted for Amiya will vote for Ramya, and another 10% who would have
otherwise voted for Amiya, will not vote at all.
• If Ramya runs a campaign attacking Amiya and Amiya runs a campaign focusing on issues, then 20% of the
students who would have otherwise voted for Ramya will vote for Amiya, and another 5% who would have
otherwise voted for Ramya, will not vote at all.
• If both run campaigns attacking each other, then 10% of the students who would have otherwise voted for
them had they run campaigns focusing on issues, will not vote at all

Video Explanation

Which of the following options best describes the number of vacant houses in Row-2?
Video Explanation

Which of the following houses are definitely occupied?
Video Explanation

How many houses are vacant in Block XX?
Video Explanation

The schematic diagram below shows 12 rectangular houses in a housing complex. House numbers are mentioned in the rectangles representing the houses. The houses are located in six columns – Column-A through Column-F, and two rows – Row-1 and Row-2. The houses are divided into two blocks - Block XX and Block YY. The diagram also shows two roads, one passing in front of the houses in Row-2 and another between the two blocks.
Some of the houses are occupied. The remaining ones are vacant and are the only ones available for sale.
The road adjacency value of a house is the number of its sides adjacent to a road. For example, the road adjacency values of C2, F2, and B1 are 2, 1, and 0, respectively. The neighbour count of a house is the number of sides of that house adjacent to occupied houses in the same block. For example, E1 and C1 can have the maximum possible neighbour counts of 3 and 2, respectively.
The base price of a vacant house is Rs. 10 lakhs if the house does not have a parking space, and Rs. 12 lakhs if it does. The quoted price (in lakhs of Rs.) of a vacant house is calculated as (base price) + 5 × (road adjacency value) + 3 × (neighbour count).
The following information is also known.
1. The maximum quoted price of a house in Block XX is Rs. 24 lakhs. The minimum quoted price of a house in block YY is Rs. 15 lakhs, and one such house is in Column-E.
2. Row-1 has two occupied houses, one in each block.
3. Both houses in Column-E are vacant. Each of Column-D and Column-F has at least one occupied house.
4. There is only one house with parking space in Block YY.
