Answer 2

let the full marks be " x "

Rajani has scored 295 marks , if she would had scored 25 more marks then she would had passed the examination,

So, passing marks :

=》320

passing percentage ( P% ) :

=》

`40 = (passing \: \: marks)/(total \: \: marks) * 100`

=》

`40 = (320)/(x) * 100`

`x = 8 * 100`

=》

`x = 800`
