Answer 1

let pass percentage = x
A scored 30%
failed by 15 marks
B scored 40% 35 marks more than required to pass.
A.T.Q
30%x +15=40%x -35
30x/100 + 15 =40x/100 -35
3x/10 - 4x/10= -35-15
-x/10 = -50
x/10= 50
x = 500

Answer 2

Step-by-step explanation:

Let the number be x

A scored =30%

and failed by = 15 marks

B scored = 40%

and obtained = 35 marks

According to the question

=15x+35x= 40%-30%

=50x=10%

=x=10/50

A failed by 15 marks

=15x=10/50

=x=10×15/50

=x=3%

The pass percentage

=30%+3%

=33% (ans)
