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.
