Passage / Data

Answer the questions based on the given data on the tourism sector in India.

​​​​​​​

Let ‘R’ be the ratio of Foreign Exchange Earnings from Tourism in India (in US $ million) to Foreign Tourist Arrivals in India (in million). Assume that R increases linearly over the years. If we draw a pie chart of R for all the years, the angle subtended by the biggest sector in the pie chart would be approximately:

Answer & solution

  • A

    24

  • B

    30

  • 36

  • D

    42

  • E

    48

Solution

The value of R for each year is as shown below:

When a pie-chart is made using the values of R, the value for 2011 forms the largest sector. Also, the total value of R is 26415.49.

Observe that the value of R in 2011 is approximately 10% of the total. So, the angle that it subtends at the centre is 10% of 360 i.e. 36 degrees.

Hence, option (c).
