Directions: Study the following data carefully and answer the question...
Given data:
- Number of commuters commuting only by trains = 17171
- Number of commuters commuting only by bikes = 7359
- Number of commuters commuting only by bus = 22077
- Number of commuters commuting only by private cars = 14718
- Number of commuters commuting only by autos = 4906
- Number of commuters commuting only by taxis = 7359
- Number of commuters commuting by bus and trains = 26983
- Number of commuters commuting by autos and trains = 9812
- Number of commuters commuting by bus and autos = 12265
Calculation:
To find the difference between the total number of commuters commuting by bus and autos, we need to calculate the total number of commuters commuting by bus and the total number of commuters commuting by autos, and then subtract the two.
Total number of commuters commuting by bus:
- Number of commuters commuting only by bus = 22077
- Number of commuters commuting by bus and trains = 26983
- Number of commuters commuting by bus and autos = 12265
To calculate the total number of commuters commuting by bus, we need to add the number of commuters commuting only by bus and the number of commuters commuting by both bus and trains or bus and autos, but we need to subtract the number of commuters commuting by both bus, trains, and autos once because they are counted twice in the above numbers.
Total number of commuters commuting by bus = 22077 + 26983 + 12265 - 26983 = 34342
Total number of commuters commuting by autos:
- Number of commuters commuting only by autos = 4906
- Number of commuters commuting by autos and trains = 9812
- Number of commuters commuting by bus and autos = 12265
To calculate the total number of commuters commuting by autos, we need to add the number of commuters commuting only by autos and the number of commuters commuting by both autos and trains or bus and autos, but we need to subtract the number of commuters commuting by both bus, trains, and autos once because they are counted twice in the above numbers.
Total number of commuters commuting by autos = 4906 + 9812 + 12265 - 9812 = 17171
Difference:
Total number of commuters commuting by bus = 34342
Total number of commuters commuting by autos = 17171
Difference = Total number of commuters commuting by bus - Total number of commuters commuting by autos
Difference = 34342 - 17171 = 17171
Therefore, the difference between the total number of commuters commuting by bus to the total number of commuters commuting by autos is 17171.
