Q1. FreshGro is analysing its delivery performance across three cities. The dataset contains delivery information and FreshGro wants to determine which city has the most efficient delivery system. Efficiency is measured using the formula.
Refer Referance Image for the formula.
FreshGro also wants to explore how traffic conditions impact delivery efficiency.
The dataset includes the following fields.
Refer table from the Referance Image.
FreshGro provides the following sample dataset.
Refer table from the Referance Image.
Question:
1. How do traffic conditions (Low, Moderate, High) impact the efficiency scores for City A?
2. Based on the overall analysis, which city is the most efficient?

Q2. Scenario: FreshGro, an online grocery delivery platform, is analysing its delivery efficiency in a specific region. Delivery time depends on the distance between the warehouse and customers, as well as the weight of the orders, with heavier orders resulting in slower deliveries.
The platform’s delivery vehicle operates under the following constraints:
Average Speed (no load): 50 km/h.
Weight Impact: For every additional kilogram of the order, the speed decreases by 1%.
Distance Impact: Delivery times are calculated using the adjusted speed.
A route consists of deliveries to the following customers:
Customer A: 15 km away, order weight 10 kg.
Customer B: 20 km further from Customer A, order weight 15 kg.
Customer C: 10 km further from Customer B, order weight 5 kg.
Question: What is the total time taken to complete the deliveries to all customers?

Q1. Scenario: Alex, an engineer, is managing a communication system designed to help forest rangers monitor animal sounds from eight locations in the forest. The system uses a multiplexer (MUX) and demultiplexer (DEMUX) to process sound signals from eight sensors (S1 to S8), each capturing the sound of a different animal. The sounds are programmed to play sequentially for 30 seconds each in the following order:
Bird chirping (S1), Frog croaking (S2), Tiger growling (S3), Elephant trumpeting (S4), Monkey chattering (S5), Cricket chirping (S6), Hyena laughing(S7), Wolf howling (S8).
This sequence creates a complete cycle lasting 4 minutes (8 animals Ă— 30 seconds each).
Starting in the 3rd cycle, Alex notices an issue with the sensor capturing the tiger growl (S3), as it transmits for only 20 seconds instead of the intended 30 seconds. This error causes the sounds of the subsequent animals to play earlier than expected, and the cycle gradually becomes misaligned.
By the 7th cycle, the system is so out of sync that the wolf howl (S8) is playing during a time slot when, according to the original schedule, a different animal’s sound should have been heard.
Question: In the 7th cycle, when the wolf's howl (S8) is playing out of sequence, which animal's sound should have been playing according to the original schedule?

Q2. Scenario: Edward, an electronics engineer, is designing a device to help forest rangers monitor animal sounds from eight locations in a forest. The device uses a special electronic switch called a Multiplexer (MUX) to pick one sound at a time from the eight sound sensors (labelled S1 to S8) and transmit it to a radio receiver. The MUX has three control switches (I2, I1, I0) that determine which sensor’s sound is played. A microcontroller updates these switches every 5 seconds to play the sounds sequentially. However, a problem in the device’s program is causing the switch to run slower than intended, taking 5.5 seconds to move from one sound to the next instead of 5 seconds. At 2 minutes into the cycle, Edward notices that the sound expected from Sensor S8, which should capture a wolf howling, is not audible. Instead, another sound is being played due to the timing issue.
Question: If the device runs 0.5 seconds slower per step, which animal sound is playing on the radio at the 2-minute?
