    MTNL (JTO/JAOS) EXAM ----HELD ON 18/09/2005.

    there were 170 q's  ,out of which 100 technical and 70 counts for 
    aptitude.
    time limit was 2 hours. 30 minutes were previusly given for filing the 
    entry.exam stared around 10 o clock.

    *there were no g.k question
    note----->>>  
    *approx 10 question were also in sail 2005 examination(management 
    trainees)
