Answer 2

Answer:

Step-by-step explanation:

Unitary method :-

In 100 marks paper --> 60 marks

In 1 mark paper --> 60/100 => 3/5marks

∴ In 75 marks paper --> (3/5)*75 => 45 marks.

You can also solve this by equating their ratios :-

Let his marks be x in 75 marks paper.

= 60/100 = x/75

=> 0.6 = x/75

∴ x = 75*0.6 => 45 marks.
