Correct Answer - Option 1 :

11:00 AM


Given,

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

Calculations:  

 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
