(a)1450
(b)1520
(c)1540
(d)2000
(e)None of these
Answer
Answer (as printed): B
Explanation
Let the maximum marks be $x$. Then, 76\% of $x+480$ $$\begin{aligned} & =x \Rightarrow x-76 \% \text { of } x=480 \Rightarrow 24 \% \text { of } x=480 \\ & \Rightarrow \frac{24 x}{100}=480 \Rightarrow x=\left(\frac{480 \times 100}{24}\right)=2000 . \end{aligned}$$ ∴ Marks scored by Rajan = 76\% of 2000 $$=\left(\frac{76}{100} \times 2000\right)=1520 .$$
