Trains A and B start from Chennai and Hyderabad towards Hyderabad and...

Train A stops after every 200 Km, B after every 160 km.

Train A to reach 1st stop will take (200 kms away) = 200/80 = 2.5 hours = 2 hrs 30 Mins.

So, Trains A will leave 1st stop at 2 hrs 30 Mins + 10 Mins = 2hrs 40 Mins = 1:40PM

Similarly, at 4:20 PM (1:40 PM + 2 hours 40 minutes), train A will leave 2nd stop at a distance of 400 kms from Chennai.

Now consider, train B at 4:20 PM.

B Starts at 1:00PM, 1st stop after 160/100 = 1.6 hours = 96 mins.

So, at 1:00PM +96 mins + 10 mins, it will leave 1st stop = 2:46 PM

Next stop will be at 2:46 PM + 96 mins = 4:22 PM

And B will leave its 2nd stop, which is at a distance of 320 km from Hyderabad at 4:32 PM.

Train A 4:32 PM will be at : 400 kms + 80/5 (12 mins = 1/5 hours) = 416 kms from Chennai.

Now we can take their combined speeds as they both will meet before the next stop.

Distance between them at 4:32 PM = 800 - (416 + 320) = 64 km

Relative speed = 100 + 80 = 180 kmph

Time taken = 64/180 hours = 21.33 minutes.

So, they will meet at 4:32 PM + 21.33 minutes = between 4:53 PM and 4:54 PM
