The given table shows the number of seats reserved in different classes in a train on six days of a week. The number of seats available in each class is given in brackets. Study the table and answer the questions that follow.
The total vacant seats in AC $$1^{st}$$ Class on all the given six days is what percentage of the average number of reserved seats in 2 Class Non-AC on Wednesday and Saturday?
Solution
Calculating the vacant seats in AC Tier I class, gives us the data
Average number of reserved seats in 2nd Class Non-Ac on Wednesday and Saturday is $$\frac{\left(840+760\right)}{2}=800$$
Total number of vacant seats in AC I tier are $$50+30+35+25+20+12=172$$
The required percentage is $$\frac{172}{800}\times\ 100=21.5\%$$
Therefore, Option A is the correct answer.
