hi,

see gate score is valid to admission in m.tech or get work opportunity at psu. However the cutoff score for public sector undertakings varies with the factors like number of applicant, questions difficulty level of gate, number of vacancy etc. however it is difficult to suggest that securing 50+ or around 50 will secure your job at psu. psu hiring includes stages of selection process like group discussion, written test/ Personal interview rounds.

so my suggestion is study harder , give your best and secure marks as much as possible.
