Correct Answer - Option 3 : 640
Given:
If Raushan got 25% marks and failed by 64 marks and he had 40% marks he would have secured 32 marks more than the pass marks.
Calculation:
Let the total marks = x
According to question,
X × 25% + 64 = X × 40% - 32
⇒ X × 40% - X × 25% = 64 + 32
⇒ X × 15% = 96
⇒ X × (15/100) = 96
⇒ X = 640
∴ The maximum marks in the examination is 640.
