In an examination it is required to get 40% of the aggregate marks to pass. A student get 261 marks and is declared failed by 4% marks. What are the maximum aggregate marks a student can get ?

Let the maximum marks be x.
Then,
$$\eqalign{ & \left( {40 - 4} \right)\% {\text{ of }}x = 261 \cr & \Rightarrow 36\% {\text{ of }}x = 261 \cr & \Rightarrow \frac{{36}}{{100}}x = 261 \cr & \Rightarrow x = \left( {\frac{{261 \times 100}}{{36}}} \right) \cr & \Rightarrow x = 725 \cr} $$
