Hello Ram

If you consider this year's competetion for PSU's then it will be tough as the question was bit easy this time. But still you can get shorlisted for various PSU's if you consider last year's cutoff's for OBC's.

Various PSu's in which you can get shorlisted are :

THDC( last year it was 67 so this year it will be high)

NPCIL (Surely)

BEML 

BHEL

CEL

NTPC( Lat year it was 59.56 for PBC's, so chances are high)
