In the above table, scores and numbers of people are shown. If the median score is not represented as the score shown on the table, which of the following scores can be the value of x?

A. 2

B. 3

C. 4

D. 5

E. 6

Total number of people \(= 2+8+x+7+8=25+x\)

if \(x\) is even the then total number of people will be

ODD, hence the median will be the mid value. As it is mentioned that the median is not represented in the chart and mid value will be a number from the chart, so it implies that \(x\) is

not EVEN. So option A, C & E are out

so \(x\) is either \(3\) or \(5\). if \(x\) is \(3\), then the total number will be \(25+3=28\), hence the median will be mid value of 14th & 15th number. as 14th & 15th number in this case will be same \((a+1)\). Hence the median will be from the chart which is not possible.

So \(x=5\)

Option
