What is the overall percentage of Tarun ?


A) 52.5%

B) 55%

C) 60%

D) 63%

E) 64.5%

Answer:

Option C

Explanation:

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.

Total maximum marks of all the 6 subjects = (150 + 130 + 120 + 100 + 60 + 40) = 600.

Overall percentage of Tarun = $\frac{360}{600}\times100$% = 60%.
