Question

the average height of a family of six members is 162 cm if the height of 5 members are 154 cm,156 cm, 160 cm, 159 cm, and 158 cm find the height of sixth family member​

Answer 1

Let height of sixth member be x cm.

$= > \frac{154 + 156 + 160 + 159 + 158 + x}{6} = 162$

$= > 787 + x = 972$

$= > x = 972 - 787$

$= > x = 185$

Hence, height of sixth member of family is 185 cm.

Hope this answer helps you ^_^ !
