Question Numbers (25 to 29): 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.
What is the maximum possible quoted price (in lakhs
of Rs.) for a vacant house in Column-E?
