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 26 seconds, what is the ratio of their speeds? Pick
A) 1:3	B) 9:1	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 = 26 s   = (27x + 17 y)/(x+y) = 26   = (27x + 17 y)/ = 26(x+y)   = x = 9y   =x/y = 9/1   Answer :9:1
