A Train T1 starts from Ranchi to Patna at 8 am and reaches at 12 noon. A second train T2 starts at 8 am from Patna reaches Ranchi at 1 pm. When did the two train cross each other? Correct Answer 10:13 am

Time taken by train T1 to complete its journey = 4 hours

Time taken by train T2 to complete its journey = 5 hours

Ratio of speeds of trains T1 and T2 = (Time taken by train T2)/(Time taken by train T1) = 5/4

Ratio of distances travelled by trains T1 and T2 = 5/4

Time taken by trains T1 and T2 to cross each other = (5/9) × 4 = 20/9 = 2 hours 13 minutes

Thus, both the trains T1 and T2 will cross each other at 10:13 am.

There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
