Solution and Answers :



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
