Answer 2

The maximum marks of the exam is 320.

Step-by-step explanation:

Given:

A student scores 75% and fails by 12( 1/2)% mark.

The pass marks are 280.

To Find:

The maximum marks of the exam.

Solution:

Let the maximum marks of the exam is p.

As given-A student scores 75% and fails by 12( 1/2)% mark.

Student score marks $=p \times\frac{75}{100} =0.75p$

Fails by marks =$=p \times\frac{12.5}{100} =0.125p$

Hence. the required pass marks = $=0.75p+0.125p=0.875p$

As given - the pass marks are 280.

$0.875p=280$

$p=\frac{280}{0.875}$

 $= 320$

Thus,the maximum marks of the exam is 320.
