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 difference between the total vacant seats in all the five classes on Thursday and the total vacant seats in AC III Tier on all the given six days is approximately what percentage of the total reserved seats in the Non-AC Classes on Thursday and Saturday?
Calculating vacant seats on Thursday and AC III gives us the data,
Total Vacant seats on Thursday are: $$100+40+80+140+25=385$$
Total vacant seats in AC III are: $$160+90+140+80+150+120=740$$
The difference between them; $$740-385=355$$
Total reserved seats in Non-Ac on Thursday and Saturday are; $$800+360+760+320=2240$$
The required percentage is $$\frac{355}{2240}\times\ 100\approx\ 15.8\%$$
Therefore, Option B is the correct answer.
