Correct Answer - Option 1 :
Distance between the two cities X and Y is 330 km.
A train starts from X at 8 a.m. and travels towards B at 60 km/hr.
Another train starts from Y at 9 a.m. and travels towards A at 75 km/hr
Distance by train started from X in one hour = 60km/hr
remaining distance = 330 – 60 = 270km
time = distance / speeda + speedb
time = 270/135
time = 2 hours
that means they both reach at 11:00 AM
∴ The required answer is 11:00 AM
