Answer 2

Ajay scored 25 % marks more than aprita

Solution:

Let the marks of Ajay be 100x

Then,

Arpita scored 20% marks less than Ajay

Marks of Arpita = 100x - 20 % of 100x

Marks of Arpita = 100x - 20x

Marks of Arpita = 80x

Difference between ajay and arpita mark = 100x - 80x = 20x

How many % marks Ajay scored more  than Arpita?

$Percent\ marks = \frac{difference}{arpita\ mark} \times 100\\\\Percent\ marks = \frac{20x}{80x} \times 100\\\\Percent\ marks = 0.25 \times 100\\\\Percent\ marks = 25 \%$

Thus Ajay scored 25 % marks more than aprita
