Q1. A tech lab in India is receiving large data files from two international research centers — one located in Singapore and the other in Johannesburg, South Africa. Both centers begin transmitting their files at exactly 10:00 AM local time in their respective countries.
File Transmission Details:
- Singapore is uploading a file named projectData_Singapore.zip (6GB) at a speed of 90 Mbps.
- South Africa is uploading a file named projectData_Southafrica.rar (4 GB) at a speed of 60 Mbps.
Time Zone Differences:
- Singapore is 2 hours and 30 minutes ahead of India.
(For example, if it’s 10:00 AM in India, it’s 12:30 PM in Singapore.)
- South Africa is 3 hours and 30 minutes behind India.
(For example, if it’s 10:00 AM in India, it’s 6:30 AM in South Africa.)
System Behavior:
Files are split into 500 MB chunks. Uploading and downloading happen one chunk at a time, simultaneously. Once a chunk is fully uploaded to India, downloading starts immediately.
Constraint:
India’s internet speed is limited to 80 Mbps, so downloading cannot exceed this speed. The arrival time of each chunk depends on the sender’s upload speed.
Data Tip:
- 1 GB can mean different things for storage and internet speed.
- Uppercase B = Byte (file size), lowercase b = bit (data speed), and 1 Byte = 8 bits
Question: Once each chunk has finished uploading, India begins downloading it automatically. Based on the image, identify which progress bar accurately shows the download status on India’s system.
Q2. Two international branches — one in Tokyo, Japan (🇯🇵) and another in Moscow, Russia (🇷🇺) — are each sending data files to their respective headquarters based in India. Both branches begin transmitting their files at exactly 10:00 AM local time in their respective cities.
File Details:
- Tokyo, Japan is uploading a file named projectData_Japan_.zip (8 GB) at a speed of 170 Mbps.
- Moscow, Russia is uploading a file named projectData_Russia.rar (3 GB) at a speed of 109 Mbps.
Time Zone Differences:
- Japan is 3 hours and 30 minutes ahead of India.
(Example: If it is 10:00 AM in India, it is 1:30 PM in Japan)
- Russia (Moscow) is 2 hours and 30 minutes behind India.
(Example: If it is 10:00 AM in India, it is 7:30 AM in Russia)
Constraint:
India’s internet server has a maximum download speed of 136 Mbps, which means no file can be downloaded faster than this limit. Once a file has been fully uploaded from a branch, the download to the Indian server begins automatically, using the maximum available speed of up to 136 Mbps limited.
Data Tip:
- 1 GB isn't always the same! It may be measured differently depending on whether it's used for computer storage or internet data transfer.
- An uppercase B stands for Byte (used for file size), while lowercase b stands for bit (used for data transfer speed). Remember, 1 Byte = 8 bits.
Question: Based on the image, identify the progress bar that most accurately represents the download status of each file on India’s system.

Q1. The Scenario: An AI enthusiast is developing a model that can identify which 2D nets can be accurately folded into complete 3D solids. The model analyses flat patterns and predicts whether they will form complete solids when folded. To test its accuracy, the model is presented with five different nets. Some of these nets can be folded into 3D solids, while others cannot form closed solids.
Question: Which of the following nets will the model correctly identify as 3D solids?
Q2. The Scenario: An AI enthusiast is developing a model that converts 2D sketches into 3D shapes using inputs drawn on a trackpad. The system traces shapes based on the movement of a single point (like a pen) and then attempts to generate a valid 3D form by extrude or folding the 2D sketch.
However, due to a hardware calibration issue in the trackpad’s gesture identification system, the AI is currently limited by the following constraints.
Drawing Constraints:
- The model can only move one unit of length at a time in any direction.
- It cannot move in the same direction more than once (i.e., no repeated directional moves).
- It can move in only four directions while drawing: left, right, up, and down.
- Immediate reversals are not allowed:
a) Right followed immediately by Left — and vice versa — is not allowed.
b) Down followed immediately by Up — and vice versa — is not allowed.
- Each move draws a straight line segment of one unit in length, which becomes part of the overall shape.
Question: Given these constraints, which of the following 2D shapes can be accurately drawn and generated by the model without breaking any movement rules?
