Boston 6 p.m. = Frankfurt 11 p.m.
Travelling time = 7 a.m. - 11 p.m. = 8 hrs.
From Frankfurt to India = 8 hrs.
Time taken for travelling = 8 hrs. + 8 hrs. = 16 hrs.
Average speed = Total distan⁡ce / Time taken
= 12000 / 16
= 750

Note the following steps:

Step 1: Possible arrangements:

All the above with E and C interchanged are also valid arrangements.

The first three arrangements cannot be true, as D and F have to fit in with D two floors above F. 

Step 2:

The second alternative is not possible since C cannot live next to F.  Hence,

Step 3:  

B

Nature, Anthropos (Man), Society, Shell and Network are the 5 elements of Ekistics. Ekistics theory   is a theory to explain settlement (human settlement) developed by Doxiadis.

Bailplug are used to close the bore from the bottom to prevent suction of gravel. Typical components of a rainwater harvesting pit/ recharge well is shown below:

Agenda 21 is a comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, Governments, and Major Groups in every area in which human impacts on the environment.
Agenda 21, the Rio Declaration on Environment and Development, and the Statement of principles for the Sustainable Management of Forests were adopted by more than 178 Governments at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro, Brazil, 3 to 14 June 1992.
Sustainable development takes care of forests, wildlife and environmental pollution

As per NBC, the area of habitable room shall not be less than 9.5 sqm, where there is only one room with a minimum width of 2.4 m. Where there are two rooms, one of these shall not be less than 9.5 sqm and the other not less than 7.5 sqm, with a minimum width of 2.1 m.

Rain water harvesting potential = Area of catchment × runoff coefficient × annual average rainfall
= (150 × 0.85 × 628) + (90 × 0.15 × 628)
= 80070 + 8478 = 88548 L per year

There are 42 UNESCO World Heritage Sites in India (as of September 2023 when last addition to the list was done). Santiniketan, established by Nobel laureate Rabindranath Tagore, becomes the 41st site to be declared a world heritage site in India in September 2023. The UNESCO also included the Sacred Ensembles of the Hoysalas m Karnataka in the list m September 2023. This takes the total number of UNESCO World Heritage sites in India to 42.

Hazen William's nomogram is used to find the required size of pipe for a water-supply system. The nomogram generally has four lines; Rate of flow, Diameter of pipe, Head- loss per unit length (gradient) and Velocity of flow. Any two known parameters on these give four lines are marked and joined with a line segment. The points where this line segment intersects the other two lines of nomogram will determine those respective parameters.

The correct sequence is P waves à S waves à  Surface waves.

Harris and Ullman argued that cities do not grow around a single nucleus but several separate nuclei. Each nucleus acts like a growth point. Also, some activities require specialized facilities, example- port can only be developed near shore.

No exit doorway shall be less than 1000 mm in width except assembly buildings, where door width shall be not less than 2000 mm. Doorways shall be not less than 2000 mm in height. The minimum width of tread without nosing shall be 250 mm for staircase of residential buildings. This shall be minimum 300 mm for assembly, hotels, educational, institutional, business and other buildings. The treads shall be constructed and maintained in a manner to prevent slipping. The maximum height of riser shall be 190 mm for staircase of residential buildings (A-2) and 150 mm for other buildings. The number of risers shall be limited to 12 per flight.   The use of spiral staircase shall be limited to low occupant load and to a building not exceeding 9 m in height. A spiral staircase shall be not less than 1500 mm in diameter and shall be designed to give adequate headroom.

A split-complementary color scheme uses two colors across the color wheel, with those two colors lying on either side of the complementary color. For example. Yellow's complimentary color is violet, but its split-complementary colors are blue-violet and red-violet.

Analogous hues are three color families that are adjacent to each other on the color wheel.
The subtractive colors are cyan, yellow, magenta, and black, also known as CMYK. Subtractive color begins with white (paper) and ends with black; as color is added, the result is darker.

A tetrad is four colors, that is, two pairs of complementary combinations. Tetradic color scheme examples are green with red and blue with orange. The four selected shades connected should form a rectangle within the color spectrum (not necessarily a square).

Compact City does include Higher Density, Intensified use of land and Creation of growth boundaries/ limits. Also, mixed use is also a prominent characteristic of compact city.

Let, N = total no. of dwelling units. FAR = 2.0 given.
So, total buildable area = 100 Hectare × 60% × 2.0 FAR = (100 × 0.60 × 2.0) Hectare
= (100 × 0.60 × 2.0 × 10000) m² = 1200000 sq m
As per question, 0.7N × 100m² + 0.3N × 80 m² = total buildable area
So, 0.7N × 100m² + 0.3N × 80 m² = 1200000
N = 12765

Given;
Number of household = 15,000
Occupied dwelling unit = 12,000
Homeless household = 15000 – 12000 = 3000
Dilapidated DU = 10% of 12,000 = 1200
Housing shortage = homeless + Dilapidated
= 3000 + 1200 = 4200

Net annual rent = Gross rent – Annual expenses = 7,50,000 – 75,000 = 6,75,000/-
Capitalized value = Net annual rent/discount rate = 6,75,000/0.08 = 84.375 lakh rupees

Total population of housing = Housing project site area x Gross residential density
= 0.8 - hectare x 100 ppha = 80 persons
Residential buildable area = 60% of 0.8 = 0.48 hectares
Net residential area = Population/Residential area = 80/0.48 = 166.67 ppha

The following test should be remembered in survey.
1. Azimuth test: It is done to make the line of sight perpendicular to the horizontal axis.
2.  Spire test: It is a test carried out to remove error due to non-perpendicularity of the horizontal axis and the vertical axis in surveying Instrument.                     
3. Cross- Hair ring test: This test is done to make the vertical cross-hair to lie in a plane perpendicular to horizontal axis.
4. Vertical arc test: It is done to make the vertical circle indicate zero when the line of sight is perpendicular to the vertical axis.

A represents the correct match of land use categories and their colour codes.

The key advantages of a rotary intersection are listed below:
Traffic flow is regulated to only one direction of movement, thus eliminating severe conflicts between crossing movements.
All the vehicles entering the rotary are gently forced to reduce the speed and continue to move at slower speed. Thus, none of the vehicles need to be stopped, unlike in a signalized intersection.
Because of lower speed of negotiation and elimination of severe conflicts, accidents and their severity are much less in rotaries.
Rotaries are self-governing and do not need practically any control by police or traffic signals.
They are ideally suited for moderate traffic, especially with irregular geometry, or intersections with more than three or four approaches.
Although rotaries offer some distinct advantages, there are few specific limitations for rotaries which are listed below.
All the vehicles are forced to slow down and negotiate the intersection. Therefore, the cumulative delay will be much higher than channelized intersection.
Even when there is relatively low traffic, the vehicles are forced to reduce their speed.
Rotaries require large area of relatively flat land making them costly at urban areas.
The vehicles do not usually stop at a rotary. They accelerate and exit the rotary at relatively high speed. Therefore, they are not suitable when there are high pedestrian movements.

In four step modelling, before entering the trip generation phase; the study area is demarcated. The traffic zones and their centroids are identified. Activities within the traffic zone are also identified.

Given, Traffic density = 80 PCU for 2 km. stretch

⇒ Traffic density, D = 80/2 = 40 PCU/km.

Also given, average vehicular velocity, V = 30 kmph.

We have, Flow, Q = D x V

⇒ Traffic flow, Q = 40 PCU/km x 30 km/hr = 1200 PCU/hr.
