  Let cluster of stations share 48kbps of pure aloha channel. Every station outputs frame of length 1024 bit in every 50 seconds. Then what is the maximum value of number of stations?

  The official Gate syllabus doesn't mention it but it's safer to know a bit..
  Since its pure aloha. So max Bandwidth utilization is 18% of 48Kbps.
  And its given, Each station transmits
  
  1024 bits in 50 seconds
  
  $\therefore$ In 1 second --- $\frac{1024}{50}$ bits
  Let's say there are N stations.
  
  So N*$\frac{1024}{50}$=18% of 48*1000
  
  N=$\left \lfloor 421.875 \right \rfloor$
  
  $\therefore$ N=421
