Question

6. The heights of four members of a family are 1 m 60 cm, 1 m 50 cm, 1
and 1 m 16 cm respectively. Find the average height of one member of the
family.​

Answer 1

Answer

Height of four members are 1 m 60 cm , 1 m 50 cm , 1 m 10 cm and 1m 16 cm.

• 100 cm = 1 m.

Sum of height of four members = 1m 60 cm + 1m 50 cm + 1 m 10 cm + 1 m 16 cm.

=> 4 m 136 cm.

=> 5 m 36 cm

=> ( 5 × 100 + 36 ) cm

==> 536 cm.

As we know , Average = Sum of observations/ Number of observations.

So,

Average height of one member = 536/4

=> 134 cm

=> 1 m 34 cm.
