Wipro — BGV rejection

Address:

KOLKATA,WESTBENGAL.

I got 61% in 12th WBCHSE board, which was taken from best of 5 subjects, as per the rules of WBCHSE GOVERNMENT OF WEST BENGAL, I my result I got 307 MAKRS OUT OF 500 (Best of 5 subjects).
But In Wipro BGV process they reject me For Total Mark's in my result is not above of 60%. (350 out off 600 for total 6 subject)
But in my result I got 60% then why wipro calculate aggregate marks percentage.
Time of fill application from not mention any point like that "Aggregate all subjects percentage should be 60% above".
I application from only writen 60% in Class 12.
So as per West Bengal Council Of Higher Secondary Education rules They calculate Best of 5 subjects marks and percentage. So why I am Rejected I completed all the milestone of wipro Of Campus Placement process, also I have Class 10 67% and In B tech 72% Marks and I got Offer Letter after that why I am Rejected pls look into this problem .
