Question
The temperature in a city increased from 25 degrees
Celsius to 32 degrees Celsius during the summer seasonCalculate the percentage change in temperature during this periodSolution
ATQ, To calculate the percentage change in temperature, you can use the following formula: Percentage Change = [(New Value - Old Value) / Old Value] × 100 In this case: Old Value (initial temperature) = 25 degrees Celsius New Value (final temperature) = 32 degrees Celsius Percentage Change = [(32 - 25) / 25] × 100 Percentage Change = (7 / 25) × 100 Now, calculate the percentage change: Percentage Change = (0.28) × 100 Percentage Change = 28% So, the percentage change in temperature during the summer season is 28%, and it increased by 28%.
