Q1:

What is the overall percentage of Tarun?

A 52.5%

B 55%

C 60%

D 63%

ANS:C - 60%

Aggregate marks obtained by Tarun     = [ (65% of 150) + (35% of 130) + (50% of 120)           + ((77% of 100) + (80% of 60) + (80% of 40) ]     = [ 97.5 + 45.5 + 60 + 77 + 48 + 32 ]     = 360. The maximum marks (of all the six subjects)     = (150 + 130 + 120 + 100 + 60 + 40)     = 600.

Therefore Overall percentage of Tarun = ( 360 x 100 ) % = 60%.
