An irregular solid is cut into seven pieces as shown. The pieces are neither rotated nor scaled, but are kept in a random sequence. Find the correct sequence to get the smooth form. The sequence should be written from left to right.
Shown below are three views of the same solid. Count the number of edges.
In the square ABCD, line XY is drawn parallel to the base as shown in the figure below. P and Q are any two arbitrary points on XY, forming triangles ABQ and CDP. What fraction of the area of the square is the total green shaded area?
Five square pyramids are stacked as shown in the figure below with the bottom layer consisting of four pyramids in a 2 x 2 grid. If the bottom layer consists of pyramids in 6 x 7 grid, and they are stacked in a similar manner to its maximum height, how many pyramids will the formation contain?
Solid 1, Solid 2 and Solid 3 are joined together to form a cuboid as shown in Figure 1. The cuboid is then painted from all the sides. How many surfaces are there without the paint when you separate all the three solids?

The figure shows the front view of a convex lens, which originally had only one edge. Five holes of different shapes, namely triangle, square, pentagon, hexagon and circle, were drilled through it...What is the total number of edges in the lens after the holes were drilled? 

 

A solid is shown in the figure below. The vertices ABCDEFGH form a 4 cm x 2 cm x 2 cm cuboid. The segments AI and DI are both of length 5 cm, and points I, C, G, F, B are coplanar. What is the height (in cm) of point I from the base rectangle EFGH? 

 

How many glasses will remain empty if you half-fill some of the empty glasses, from the given set of filled glasses? 

 

An intersection is a point where two or more lines/curves meet or cross. How many intersections are there in the figure given below? 

All the four-digit numbers except one is written using a single font. Identify the number that does not use the same font as the other numbers.

Find the number which will replace the question mark.

Mobility and Vehicle Design
Description: A company is planning to introduce an electric two-wheeler taxi in the city of Banaras (Varanasi) for local commuters and pilgrims. Design an electric two-wheeler taxi by identifying at least five distinct and essential factors that will make it relevant for the city of Banaras in terms of function and aesthetics.
Illustrate in perspective a still life composition with the following objects:- A plastic water bottle- A transparent half empty glass of water with a metal spoon inside it- A kitchen knife placed next to a half-eaten apple on a grey ceramic plate.
Illustrate the following scene:- A dog chases a fruit seller carrying a basket full of bananas.- A kid on a tricycle watches.
Construct two different stories using the following three terms:
Orphan, Mango, Cycle shop. Each story should not be longer than three sentences
A helmet is used to prevent head injury in risky situations. Helmets are used in many sports as well as while driving a bike. Describe five DIFFERENT creative ways you can use a helmet other than as a headgear. Sketch your ideas and write a one-line note to describe each idea.
Evaluation Criteria:
Originality, imagination and presentation.
A ball starts rolling down a slope as shown in the figure below. All units shown are in meters. The floor has very little friction. Which of the following is true after a long time?
The figure shown is an example of:

Industrial Design Description: You are provided with a base (chassis) of 100 cm x 75 cm as indicated below. It has:

  • An inbuilt motor and battery-charger system
  • Capacity to carry maximum load of 200 kg (apart from its own weight)
  • A maximum speed limit of 5 km/hr

You are free to add other parts and accessories to it in order to make it a complete and stable product.

Part A: Using this platform, imagine and sketch 3 ideas for its use in a hospital environment.

Part B: Further, develop one idea as a concept for actual implementation and:

  • List down 10 critical factors you will consider in your design.
  • Sketch and explain your concept for its functional details, features, and usage.
  • Suggest/indicate the materials and processes to manufacture the product.
  • Write a brief note explaining the concept and list the design decisions taken.

Evaluation criteria:

  • Critical thinking, identification of user needs and understanding of the context
  • Problem solving and appropriateness of the solution
  • Ability to explain details and features, sketching, presentation, and articulation
  • Knowledge of materials and processes

Communication Design
Description:
Shaaradapur is an Indian village. It has a multi-lingual, low-literate population. There is a lack of awareness on maintaining health and hygiene. This results in an outbreak of malaria. Malaria is a mosquito-borne disease and its symptoms include fever, headache, vomiting and fatigue. If left untreated, malaria can be life-threatening. So it is important that timely diagnosis and treatment are done under a trained medical practitioner at the government hospital in the village. Malaria can be prevented with mosquito control measures like draining stagnant water and spraying insecticides. Mosquito bites could also be avoided by using mosquito nets and insect repellents.
Design Task:

Design a poster for villagers with the above information on malaria to be displayed prominently at a public place. This poster has to be specific to this village and should communicate:

(a) the seriousness,
(b) the symptoms,
(c) the actions to be taken and
(d) the prevention of malaria.

Select an ideal location in the village for this poster and:

(a) Sketch to illustrate how it will be displayed at the location.
(b) Write 5 sentences justifying your selection of the location, size, and strategy in the way it is displayed.

Evaluation Criteria:

Ability to understand the design brief
Clarity of thought, articulation, creativity, and presentation.
"Fitts's law" predicts nearer, wider targets are faster to select than farther, narrower targets. Shown below are parts of two Indian language virtual keyboards X and Y that demonstrate the input of a vowel modifier (matra) in Indian scripts. In each case, the first image shows the initial interface, and the second image shows the interface after the user touches a consonant. In both cases, the user selects the desired vowel modifier by sliding his finger towards it. Which of the statements below is TRUE, as per Fitts’s law?
