Question

The test results of a class were tabulated. Who was the student whose score lies exactly in the middle of all the students in that class?

$\begin{matrix} R o l l N o & N a m e & M a r k s & R o l l N o . & N a m e & M a r k s & R o l l N o . & N a m e & m a r k s 1 & P a v a n i & 96 & 6 & G o u t h a m & 21 & 11 & A k a s h & 83 2 & M a h i b u r & 32 & 7 & P r e e t i & 85 & 12 & S a t h y a m & 78 3 & D e e p t h i & 93 & 8 & K u s h a g r a & 45 & 13 & A j u & 98 4 & K a r a n & 81 & 9 & P a v a n & 90 & 14 & A k s h i t & 65 5 & S a r o s h & 61 & 10 & V i g n e s h & 54 & 15 & A j i t & 73 \end{matrix}$

Solution

The correct option is B Sathyam
If we arrange the marks in ascending order, we will get the following table:

$\begin{matrix} R o l l N o & N a m e & M a r k s & R o l l N o . & N a m e & M a r k s & R o l l N o . & N a m e & m a r k s 6 & G o u t h a m & 21 & 14 & A k s h i t & 65 & 7 & P r e e t i & 85 2 & M a h i b u r & 32 & 15 & A j i t & 73 & 9 & P a v a n & 90 8 & K u s h a g r a & 45 & 12 & S a t h y a m & 78 & 3 & D e e p t h i & 93 10 & V i g n e s h & 54 & 4 & K a r a n & 81 & 1 & P a v a n i & 96 5 & S a r o s h & 61 & 11 & A k a s h & 83 & 13 & A j u & 98 \end{matrix}$

There are 15 students in that class.
The student whose marks lie exactly in between the marks scored by all the students is 8th student out of 15.
The student is Roll no. 12, Sathyam, who scored 78 marks.
We were able to find him so easily because we organized the data set first.
