Question

The average height of family of 6 members is 162 if the height of 5 members are 154 cm 156 centimetre 160 cm 159 cm and 158 CM find the height of 6th family member

Answer 1

Let the height of 6th member be x cm.

we know,

(154 + 156 + 160 + 159 +158 + x ) ÷ 6 = 162

=> 787 + x = 162 x 6 cm

=> x = 972 - 787 cm

= 185 cm
