(A) 55%

(B) 60%

(C) 63%

(D) 64.5%

Ans: B

Aggregate marks obtained from Tarun

= (97.5 + 44.5 + 60 + 77 + 48 + 32) = 360.

Total maximum marks of all the 6 subjects

= (150 + 130 + 120 + 100 + 60 + 40) = 600.

Overall percentage of Tarun = $$({360}/{600} × 100)%$$ = 60%.

= (108 + 96 + 84 + 96 + 102 + 78 + 60) = 624.
