Direction: Expenses (in multiples of Rs. 10,000/-) on the consumption of fuel for the official car at a regional office (RO) of a national organization during 2006 - 2010 is 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 RO 20 22 23 24 25 NA 18 17 19 18 23
If the data of RO, given in the table, is not taken into account, then what would be the NA (in multiple of Rs, 10,000/-) in 2006?
17.5
The correct answer is 17.5.
Total Sum = Mean $\times$ Number of items When a specific value is removed from the set, the sum changes, and the number of items changes. To find the new average, we calculate the new sum (original sum minus the removed value) and divide by the new number of items (original number minus 1). This problem demonstrates how changes in individual data points affect the overall average of a group. It's a common type of problem encountered when analyzing data sets.
