Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 85.50%

According to the question,

Total percentage (PT) student acquired = 90% of internal test + 95% of Assignments + 75% of external exam

⇒PT=90% of 30+95% of 30+75% of 40⇒PT=90%×30+95%×30+75%×40⇒PT=0.90×30+0.95×30+0.75×40⇒PT=27%+28.5%+30%⇒PT=85.50% \begin{aligned} & \Rightarrow P_T=90 \% \text { of } 30+95 \% \text { of } 30+75 \% \text { of } 40 \\ & \Rightarrow P_T=90 \% \times 30+95 \% \times 30+75 \% \times 40 \\ & \Rightarrow P_T=0.90 \times 30+0.95 \times 30+0.75 \times 40 \\ & \Rightarrow P_T=27 \%+28.5 \%+30 \% \\ & \Rightarrow P_T=85.50 \% \end{aligned}
