Given, 25,26,27,28,29 marks in different subject.
Mean = Sum of observations/Total number of observations
= 25+26+27+28+29/5
= 135/5
= 27
Median = (n+1/2)th observation
[ Since, N is odd]
= (5+1/2)th observation
= 3rd observation
= 27
Since, Mode = 3 median -2 mean
Therefore, = 3(27) -2(27) = 27
Hence,27 denotes mean, median and Mode
