A student secures 90%,60%,54% marks in test papers with 100,150 and 200 respectively as maximum marks. The percentage of his aggregate is

A) 64%

B) 68%

C) 70%

D) 72%

E) 65%

Option A

Total marks secured =90% of 100 + 60% of 150 +54% of 200

= $\frac{90\times100}{100}+\frac{60\times150}{100}+\frac{54\times200}{100}$

=288

Total maximum marks = $100+150+200 =450$

Aggregate % = $\frac{288}{450}\times100$

=64%
