SOLUTION

TO CHOOSE THE CORRECT OPTION

Virat obtained 18% marks in an examination and he failed by 60 marks. If passing marks are 33%, then total marks are

(1) 350

(2) 400

(3) 450

(4) 500

EVALUATION

Let T be the total marks

Now it is given that Virat obtained 18% marks in an examination

So the marks obtained by Virat

\displaystyle\sf{ = T \times  \frac{18}{100} }

\displaystyle\sf{ =    \frac{18T}{100} }

Again promotion marks are 33%

So promotion marks

\displaystyle\sf{ =   T \times  \frac{33}{100}  }

\displaystyle\sf{ =    \frac{33T}{100} }

So by the given condition

\displaystyle\sf{   \frac{33T}{100} -  \frac{18T}{100} = 60  }

\displaystyle\sf{ \implies   \frac{15T}{100}  = 60  }

\displaystyle\sf{ \implies   T= 60  \times  \frac{100}{15}  }

\displaystyle\sf{ \implies   T= 400}

Hence the required total marks = 400

FINAL ANSWER

Hence the correct option is (2) 400
