Answer
Explanation
Total marks secured = (90\% of 100 + 60\% of 150 + 54\% of 200) $$\begin{aligned} & =\left(\frac{90}{100} \times 100+\frac{60}{100} \times 150+\frac{54}{100} \times 200\right) \\ & =(90+90+108)=288 . \end{aligned}$$ Total maximum marks $=(100+150+200)=450$. $$\text { ∴ Aggregate percentage }=\left(\frac{288}{450} \times 100\right) \%=64 \% .$$
