Sensor System

To determine ripeness, the system uses the following three sensors:

- Force Sensor: Measures firmness by converting the mango’s mass (in grams) into force (Newtons)

- Colour Sensor: reads RGB values to determine skin colour

- NIR Sensor: measures Brix level to detect sugar content

Sensor Conflict Rule

Due to occasional calibration variances, the sensors may provide conflicting ripeness data. Your task is to develop a decision-making model to resolve these conflicts, based on the following logic:

- If two sensors agree on the ripeness stage, select the majority result.

- If all three sensors indicate different ripeness stages, follow the priority order below:

Brix (NIR) > Colour (RGB) > Force

Refer "Referance Image" for the "Sensor Readings for 4 Mango Samples" values

Note: The force sensor records mass in grams, but the system internally converts this to Newtons using the following formula:

Force (N)=Mass (g)×9.8 /1000

Refer "Referance Image" for the "Threshold Reference Table (Machine Sorting Logic)" values

Sorting Containers

The system directs mangoes to one of the following containers based on ripeness:

Green container → Unripe mangoes

Orange container → Ripe mangoes

Red container → Overripe mangoes

Question: Based on the sensor readings, decision model, and sorting rules, into which containers are Samples A, B, C, and D sorted, and how many mangoes does each container contain after sorting?

- Force Sensor: measures firmness (indicates ripeness)

- Colour Sensor : reads RGB values to determine skin colour

- NIR Sensor: measures Brix level to detect sugar content

Your system needs to sort 4 mango samples (A, B, C, D) into these categories: Unripe, Ripe, and Overripe.

Refer the "Referance Image" for the "Sensor Readings for 4 Mango Samples" values.

Refer the "Referance Image" for the "Sorting Rules (Ripeness Thresholds)" values.

Note: If at least 2 out of 3 sensors match the same ripeness level, the machine sorts it into that category.

Sorting Containers

The system will place each mango into one of the following containers:

Green Container – Unripe Mangoes

Orange Container – Ripe Mangoes

Red Container – Overripe Mangoes

Question: Based on the sensor readings and ripeness thresholds, into which containers are Samples A, B, C, and D sorted, and how many mangoes does each container contain after sorting?

Atlas is flying directly above Falcon in parallel alignment. However, to initiate the probe-and-drogue refuelling method, Atlas needs to move slightly ahead of Falcon while maintaining parallel flight.

Currently, Falcon One is travelling at 150 m/s, while Atlas is flying ahead at 200 m/s.

Arin begins to accelerate steadily, aiming to catch up and match Atlas's speed precisely where the horizontal gap falls within the safe zone.

Refer the 'Formula' from the referance image.

Question: Arin needs to find the minimum time at which he can match Atlas’s speed and achieve a safe horizontal gap of 15 to 24 metres. Based on the data below, which option represents the earliest valid moment to begin refuelling?

Atlas is flying directly above Falcon in parallel alignment. However, to initiate the probe-and-drogue refuelling method, Atlas needs to move slightly ahead of Falcon while maintaining parallel flight.

To refuel Falcon safely using the probe and drogue method, Falcon One must not fly directly ahead of Atlas. Instead, Arin must carefully fall behind Atlas by 15 to 24 metres before engaging the refuelling system.

Currently, Falcon One is flying slower at 192 m/s, while Atlas is cruising ahead at 200 m/s. Arin pushes the throttle steadily, increasing Falcon One’s speed by 1.6 m/s every second. He wants to know how many seconds it will take to reach the same speed as Atlas (200 m/s).

Question: How many seconds will it take for Falcon One to reach 200 m/s? At that moment, which option correctly shows Falcon One in the safe refuelling position — 15 to 24 metres behind Atlas?
