Explanation:
Krishna Express :-
Krishna Express total passengers = 1000
27% of total passengers General Class Coach = (27*1000)/100=270
17.5% of total passengers AC Class Coach = (17.5*1000)/100=175
33.5% of total passengers Sleeper Class Coach = (33.5*1000)/100=335
Remaining are First Class = 1000-(175+335+270)=220
Godavari Express :-
Total passengers 20% more than Krishna Express = (120*1000)/100 =1200
Total Number of passengers in AC coaches in both the trains
together is 410
AC passengers in Godavari = 410- AC passengers in Krishna=410-175=235
33.75% of total passengers Sleeper Class Coach = (33.75*1200)/100=405
(125/6)% of total passengers First Class = ((125/6)*1200)/100=250
Remaining passengers in General = 1200-(235+250+405)=310
Total amount will be generated from first class coaches of Krishna Express = 550*220=121000
