    Solution

    ATQ,

    Let length of Train A = LA Crosses pole in 8 sec β†’ speed = LA / 8 Crosses 300 m platform in 18 sec β†’ (LA + 300) = (LA / 8) Γ— 18 LA + 300 = (9LA)/4 4LA + 1200 = 9LA β†’ 5LA = 1200 β†’ LA = 240 Let length of Train B = LB Crosses pole in 9 sec β†’ speed = LB / 9 Crosses 300 m platform in 24 sec β†’ (LB + 300) = (LB / 9) Γ— 24 LB + 300 = (8LB)/3 3LB + 900 = 8LB β†’ 5LB = 900 β†’ LB = 180 Hence, required difference = 240 – 180 = 60 meters
