In a test a student got 30% marks and failed by 25 marks. In the same test another student got 40% marks and secured 25 marks more than the essential minimum pass marks. The maximum marks for the test were

Let the maximum marks in the examination = x.
According to the question,

=	40x	-	30x	= 50
	100		100

=	10x	= 50
	100

⇒ x =	50 × 100	= 500
	10

Aliter : Using Rule 22,
m = 30%, n = 40%, p = 25 and q = 25
∴ Maximum marks

=	100	× (p + q)
	(n - m)

=	100	× (25 + 25) = 500
	(40 - 30)
