Q: Answer-Speed of train A and train B is 90 km/hr and 36 km/hr respectively. They cross each other in 10 seco...

Let length of first train be L1 length of 2nd train be L2. So 9036518 L1L210 L1L2 350m L1- L2 50m Hence L1 200m L2 150m i Already found ii Already found iii Time taken by train A to cross a point 200m90kmph 200m25ms 8 sec iv Time taken by train B to cross a platform of length 350m 350150m36kmph 500m10ms 50 sec Hence all values can be find by given data so correct ans is option d.
