Answer 1

Given, the height of 6 girls were measured in cm and the results are as follow :
135, 150,139, 128, 151, 132


To find : Average height of the girls (in cm)


Solution :-

There is a formula for finding the Average and it is as follows :

Average = $\dfrac{Sum\:of\:all\:scores}{Total\:no\:of\:scores}$

Now, by using this formula we will find the average height of the girls.

➾ Average = $\dfrac{135 + 150 + 139 + 128 + 151 + 132}{6}$

= $\dfrac{835}{6}$

= 139.1$\overline{6}$


∴ Average height of the girls is Option 2 i.e. 139.1$\overline{6}$✔✔
