Read the values directly from the line graph for Bikes (300) and Metro (150), then simplify the ratio 300:150 to 2:1.
Number of employees who used Bike = 300, Number of employees who used Metro = 150
Ratio=Employees┬аusing┬аMetroEmployees┬аusing┬аBikeтАЛ
Read the values directly from the line graph for Bikes (300) and Metro (150), then simplify the ratio 300:150 to 2:1.
Confusing the order of modes in the ratio and writing 1:2 instead of 2:1.
Step 1: Identify Bike Users
From the given line graph, locate the data point corresponding to 'Bikes'. The number of employees who used Bikes in 2010 is 300.
Bike┬аusers=300
Step 2: Identify Metro Users
Locate the data point corresponding to 'Metro' on the graph. The number of employees who used Metro in 2010 is 150.
Metro┬аusers=150
Step 3: Calculate the Respective Ratio
Compute the ratio of Bike users to Metro users and simplify the fraction to its lowest terms: Ratio=150300тАЛ=12тАЛ=2:1
Ratio=2:1
B is correct because the ratio of employees who used Bikes (300) to those who used Metro (150) simplifies to 300:150=2:1.
Data interpretation questions frequently combine graph reading with fundamental arithmetic operations like percentages, averages, and ratios.
