Given,

average of three children  let say A= 95 cms

Height of two children let say C_1 = 97cms, C_2=92cms

Now, by using the average formula

Average(A) = (sum of all reading)/(total number of readings)

A = \frac{C_1+C_2+C_3}{3}

95 = \frac{97+92+C_3}{3} \\

multiplying both sides with '3' we get

(95*3) =97+92+C_3\\285-(97+92) = C_3\\C_3= 96cms

∴ The height of the third child is C_3 = 96cms
