wrong question....
See, the point N is not specific... i mean neither a mid point nor a particular point dividing AB in some ratio nd all... so there can be many cases formed by taking any arbitrary point N on AB..
but does the length PQ always remains constant.. If yes then why not to take the mid point of AB as N... simple...!!
which gives PQ = 8.5 cms

You are mistaken. Check your figure again. If you take the midpoint of AB as N then PQ is not 8.5cm.

why?
apply mid point theorem....!!
nd then check...!!

I'm really sorry. You are right. It is 8.5 with this question. Actually the thing is that from where I had received the question it was given that NP was perpendicular to CD. But I mistyped the question. But, now I think this was the actual question (which is fairly easy).
Sorry for the inconvenience.

You can easily solve this question by using the mid point formula and let me know your answer then I will tell mine,Let's see if they are same or not.
