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 all the given five classes on Wednesday is what percentage less than the total vacant seats in $$2^{nd}$$ Class Non-AC on Monday, Tuesday and Friday? (Correct to one decimal place)
Solution
Calculating the 2nd class non-Ac vacant seat data and Wednesday's vacant seat data, we get
Calculating the 2nd Non-AC vacant seats on Monday, Tuesday and Friday, we get, $$210+180+150=540$$
Vacant seats on Wednesday are, $$60+120+140+125+35=480$$
The percentage can be calculated as,
$$Percentage\ =\ \dfrac{\left(540\ -\ 480\right)}{540}\ \times\ 100\ =\ \dfrac{60}{540}\ \times\ 100\ =\ \dfrac{100}{9}\ =\ 11.1\%$$
Therefore, option A is correct.
