In each of the following questions a question is asked followed by three statements.You have to study the questions and all the given three statements and all the statements and decide whether any information provided in the statement are redundant and can be dispensed with while answering the questions ?
How much time will the train X take to cross another train Y running in the opposite direction ?
I.Train X crosses a signal pole in 6 secs
II.Ratio of the speeds of trains X and Y is 3:2
III.Length of the two trains together is 500 meters
To find the time taken by train X to cross train Y, we should know the sum of speed of the trains (as they are moving in opposite directions) and the sum of lengths of the train
In statement II, ratio of speed of train X : Y = 3 : 2
Thus, we cannot find the speeds of the two trains.
