Multiple choice

Each question below contains a statement followed by Quantity I and Quantity II. Find both to find the relationship among them. Mark your answer accordingly. Quantity I: The length of train if train can cross a pole in 18 seconds and a 210 m platform in 39 seconds. Quantity II: The length of platform if 200 m long train passes a pole in 20 seconds and platform in 46 seconds.

  1. Quantity I > Quantity II

  2. Quantity I ≥ Quantity II

  3. Quantity II > Quantity I

  4. Quantity II ≥ Quantity I

  5. Quantity I = Quantity II or Relation cannot be established

C Correct answer
Explanation

Quantity I: Train speed = 210÷(39-18) = 10 m/s. Length = 10×18 = 170 m. Quantity II: Train speed = 200÷20 = 10 m/s. Platform length = 10×46 - 200 = 260 m. 260 > 170, so Quantity II is greater.
