Problems on Trains will cover the basic concepts and easy to solve. Test conducted to know the logical thinking capacity of a person.
The Problems on Trains test also requires the tests to learn skills from the test as the test proceeds, challenging thinking skills.
Formula: Speed=Distance/Time
Some useful things:
To change k/h in m/s we multiply
By 5/18
Eg: 72 k/h means
72*5/18=4*5=20 m/s
To change m/sec. in k/h multiply by
18/5
Eg: 45 m/s means
45*18/5= (9*18) k/h=162 k/h
Case1: When a train crosses a man/pole/tree
Let a train a having speed is s and length L, crosses a pole in T time then,
S=L/T (Here the breadth of man, tree, pole is negligible with respect to the train)
Case2: When a train crosses a platform
Let a train having speed of S and length
L1, crosses a platform whose length is
L2 in time T, then
S=L1+L2/T
Case3: When a train crosses another running train
Let a train having speed s1 and length L1 crosses another train which is travelling in opposite direction at a speed of sS2 and length L2 in T time. Then
S1+S2=L1+L2/T
If both objects having length (L1 and L2) then the length is always sum (i.e. L1+L2)
Case 4: when a moving train crosses a man who is running
Let a train having speed s1, and length L1 crosses a man, who is running at a speed of S2 in the same direction in T time. Then
(S1S2)=L1/T
Case 5: When a moving a train crosses a man who is sitting into a moving train.
Leat a train having speed S1 and length L1
Crosses a man who is setting in another train which is travelling in opposite directions at speed of S2 and length L2 in time T.
S1+S2=L1/T
Problems on Trains Questions will be used for all competitive exams.
