Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively . If they cross each other in 22 seconds, what is the ratio of their speeds? Choose the correct choice from the following answers.
A) 1:1 B) 3:1 C) 2:3 D) 3:2 E) 3:4
Let the speed of the trains be x and y respectively   length of train1 = 27x   length of train2 = 17y   Relative speed= x+ y   Time taken to cross each other = 22 s   = (27x + 17 y)/(x+y) = 22   = (27x + 17 y)/ = 22(x+y)   = 5x = 5y   =x/y = 5/5=
