In Gopi's opinion his height is greater than 168 cm but less than 178 cm. His siter does not agree with Gopi and she thinks that Gopi's height is greater than 172 cm but less than 176 cm. His mother's view is that his height cannot be greater than 175 cm. If all of them are correct in their estimation, and Gopi's height is an integer value. What is the approx average of different probable heights of Gopi? [Ans: 174 cm] My Try: Average of Gopi's opinion: $\frac {168 + 178}{2}$ Average of Gopi's sister's opinion: $\frac {172 + 176}{2}$ Average of Gopi's mother opinion: $\frac {175}{1} = 175$ The approx average of different probable heights of Gopi = $\Large\frac {\frac {168 + 178}{2} + \frac {172 + 176}{2} + \frac {175}{1}} {3}$ Is my procedure is right? If not, tell the correct procedure. Last edited by Ganesh Ujwal; April 11th, 2018 at 02:10 AM.

This question was asked and answered two times at Free Math Help. No. It is not right as has already been explained to you.

Height range is 173175. Average must be in there.

Oh man, watching this dude is like watching a train crash live. Fascinating. Soon nobody is going to help anymore and he'll complain how nobody wants to help him. I have rarely seen somebody this entitled and rude. Very extraordinary!
