Multiple choice

Directions: In the given question, two quantities are given, one as 'Quantity 1' and another as 'Quantity 2'. You have to determine the relationship between the two quantities and choose the appropriate option. A 251 m long train crosses a bridge in 10 seconds. Quantity 1: Value of (x + 25 % of x), If speed of the train is x and the length of the bridge is 149 m Quantity 2: Value of (2y + 10 % of y), If speed of the train is y and the length of the bridge is 159 m

  1. Quantity 1 > Quantity 2

  2. Quantity 1 ≥ Quantity 2

  3. Quantity 2 > Quantity 1

  4. Quantity 2 ≥ Quantity 1

  5. Quantity 1 = Quantity 2 or Relation cannot be established

C Correct answer
Explanation

Speed = (Length of train + Length of bridge) / Time. For Q1: x = (251 + 149) / 10 = 40. Value = 40 + 0.25*40 = 50. For Q2: y = (251 + 159) / 10 = 41. Value = 2(41) + 0.1*41 = 82 + 4.1 = 86.1. Since 86.1 > 50, Q2 > Q1.
