Solution:

Vacent seat in all non AC on Wednesday

⇒(900-830)=70,(900-790)=110

and Vacent seat in all non AC on Thursday

=(500-390)=110,(500-480)=20

Total

=70+110+110+20=310

Vacent seat in all AC class on Monday, Tuesday and Friday.

=(500-480)=20,(500-450)=50

(500-500)=0

and,

(250-240)=10

(250-230)=20

(250-210)=40

,
and

(150-145)=5

(150-120)=30

(150-130)=20

Total

=20+50+0+10+20+40

+5+30+20=195

∴

Required ratio

=310: 195=62: 39
