Akash Debbarma who got 30% marks in an examination failed by 50 marks. Rohan Deb who got 320 marks failed by 30 marks. What is the maximum marks in the examination ?
Answer: A
The maximum marks are 1000.
Rohan's score tells us the pass mark: he got 320 and fell 30 short, so the pass mark is 350. Akash got 30% of the maximum M and fell 50 short of the same pass mark:
\[ \begin{aligned} 0.30M + 50 &= 350 \\ 0.30M &= 300 \\ M &= 1000 \end{aligned} \]
Check: 30% of 1000 is 300, which is 50 below 350. With 1200 or 900 the two candidates' figures would give different pass marks, so they cannot be right.
