Answer: 123.5 centimeters
Step-by-step explanation:
Let sum of observations be S and number of observations be n.
Average A=
The average height of 4 children is (15h-3)

Also, when two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters the sum of heights of 6 children will be

Now, Average height of 6 students=
At h=9
Average height of 6 students=
9e + 4 = 14 + 8e
9e = 10 + 8e (Subtract 4 from both sides)
e = 10 (Subtract 8e from both sides)
