Question

In an examination, a student requires 40% of the total marks to pass. If Rupa gets 185 marks and fails by 15 marks, find the total marks.

Answer 1

$\begin{array}{l}\text{Let}\mathit{\text{x}}\text{be}\text{the total marks.}\\ \text{According to the question, we have:}\\ \text{4}0\%\text{of}\mathit{\text{x}}=\text{185}+\text{15}\\ \Rightarrow \frac{40x}{100}=200\\ \Rightarrow \text{4}0x=\text{2}00\times \text{1}00\\ \Rightarrow 40x=20000\\ \Rightarrow x=\text{5}00\\ \therefore \text{Total marks}=\text{5}00\end{array}$
