Train X and Train Y running in opposite directions crosses each other in 25 seconds. Find the length of Train X.
Statement I: Speed of Train X to Train Y are in ratio 3:2.
Statement II: Train X and Train Y crosses a man in 20 seconds and 15 seconds respectively.
Let the length of Train X and Train Y be L1 and L2 respectively and let the speed of Train X to Train Y be 3x and 2x respectively. Length of Train X, => L1/3x = 20 => L1 = 60x Length of Train Y, => L2/2x = 15 => L1 = 30x Train X crosses Train Y in 25 seconds, => (60x + 30x)/(3x + 2x) = 25 => 90x/5x = 25 => 90x = 125x Neither Statement I nor statement II is sufficient to answer the question.
