Answer:  शाळेतील पहिली ते सातवीच्या वर्गात अनुक्रमे  30,22,25,28,31,20 आणि 26

1st to 7th class of the school children  30,22,25,28,31,20 and 26   respectively

To Find :   वर्गात सरासरी किती मुले

average number of children in the class

1 28

2 23

3 29

4 26

Solution:

Mean=\overline{x}=\dfrac{\sum x}{n}

∑x   = ( 30 + 22 + 25 + 28  + 31 + 20 + 26)

=   182

n  = 7

Mean=\overline{x}=\dfrac{182}{7}

Mean = 26

वर्गात सरासरी 26 मुले

average number of children in the class = 26
