B)0.5

Mean=sum of data/no. of data

Eg.

Find the mean of A,B = A+B (Their sum)/(2(Their number)) 

So the question already gave you the number of data which is 2105

and the sum of the data which is 1008.08 

just apply the formula

1008.08/2105=0.47.... rounded to the nearest tenth would be 0.5 which is option B
