Expenses (in multiples of ₹10,000/-) on consumption of fuel for the official car at a regional office (RO) of a national organization during 2006-2010 are given below in a tabular form along with the National Averages (NA) during the said period. It is given that there are five ROS.
| Year | 2006 | 2007 | 2008 | 2009 | 2010 |
| R) | 20 | 22 | 23 | 24 | 25 |
| NA | 18 | 17 | 19 | 18 | 23 |
If the data of the RO is represented through a pie chart, then what would be the central angle (nearest to a degree) of the sector corresponding to the year 2008?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 73°.
Total RO expenses = 20 + 22 + 23 + 24 + 25 = 114
Central angle = (23/114) × 360° = 73° (approx)
