Mathematics Question on Percentage
Shatabadi Express has a capacity of 500 seats of which 10% are in the Executive Class and the rest being Chair Cars. During one journey, the train was booked to 85% of its capacity. If Executive Class was booked to 96% of its capacity, then how many Chair Car seats were empty during that journey?
75
73
71
None of these
73
Solution
The correct option is (B): 73
To find how many Chair Car seats were empty during the journey, we can follow these steps:
1. Determine the number of Executive Class and Chair Car seats:
- Total seats: 500
- Executive Class seats: 10% of 500=0.10×500=50
- Chair Car seats: 500−50=450
2. Calculate the total booked seats:
- The train was booked to 85% of its capacity:
Total booked seats=85%×500=0.85×500=425
3. Calculate the booked Executive Class seats:
- Executive Class was booked to 96% of its capacity:
Booked Executive Class seats=96%×50=0.96×50=48
4. Determine the booked Chair Car seats:
- Total booked seats are 425, and the booked Executive Class seats are 48:
Booked Chair Car seats=425−48=377
5. Calculate the empty Chair Car seats:
- Total Chair Car seats are 450:
Empty Chair Car seats=450−377=73
Thus, the number of empty Chair Car seats during that journey is 73.
