Question

In an examination, Ramesh secured 574 marks and Rekha secured $76\%$ of the total marks. If Ramesh secured $82\%$ of the total marks, the difference in their mark is _______.

Answer 1

Ramesh secured = 574 marks

Rrekha secured = 78 %

Ramesh secured 82 %

$82\%x=579$

$\frac{82}{100}x=574$

$x=\frac{57400}{82}$

$x=700$

Now 76 % of 700

$\frac{76}{100}\times 700$

Rekha’s =532

Now difference of marks

$574–532=42$
