y=x−30

4

y

=x−30

⇒x=

4

y

+30.....(1)

Also,

100

50

y=x+20

2

y

=x+20

⇒

2

y

=

4

y

+30+20(From (1))

⇒

2

y

−

4

y

=50

⇒

2

y

=50

⇒y=50×2=100

Substituting the value of y in equation (1), we have

x=

4

200

+30=50+30=80

Hence the minimum passing marks are 80 and the maximum marks are 200.
