suppose both train started with the same time=8 am
speed of the 1st train =20 kmph
speed of the 2nd train =25 kmph
sum the speed of both train=20+25=45kmph
reach the train in a hour 90km
and left 20km that we suppose for Same time
90+20=110km
both train walk 110km in 2hours
Now,
the both train started in 8:00 am
8+2=10:00 am
the correct option is B
