Question

19. Average height of 5 students 1 m 16 cm. A new student of height 1 m
18 cm joined them. What is the average height of the 6 students.​

Answer 1

Answer:

Average height of 5 students - 1 metre 16 cm

= 1.16 m

Height of the new student = 1 metre 18 cm

= 1.18 m

So, the average of the 5 students will be

$\frac{1.16 + 1.18}{2} \\ = \frac{2.34}{2} \\ = 1.17 \: m$

So, their average will be 1.17 m or 1 m 17 cm.
