      Question

      Ajay and Vishal left the place ‘X’ with different

      speeds which are in the ratio 4:3 respectively. Ajay left the place 36 seconds after Vishal. If after 72 seconds of the departure of Vishal, Ajay is 80 meters apart from Vishal, then find the speed of Vishal.
      A 16 km/hr Correct Answer Incorrect Answer
      B 12 km/hr Correct Answer Incorrect Answer
      C 15 km/hr Correct Answer Incorrect Answer
      D 20 km/hr Correct Answer Incorrect Answer
      E 18 km/hr Correct Answer Incorrect Answer

      Solution

      Let the speeds of Ajay and Vishal be 4x and 3x km/hr respectively. Distance covered by Vishal in 72 seconds = 3x x (5/18) x 72 = 60x m Distance covered by Ajay in 36 seconds = 4x x (5/18) x 36 = 40x m According to the question, => 60x – 40x = 80 => x = 4 Therefore the speed of Vishal = 3x = 12 km/hr
