    Question

    Ajay and Vishal left the place ‘X’ with different

    speeds which are in the ratio 3:2 respectively. Ajay left the place 30 seconds after Vishal. If after 54 seconds of the departure of Vishal, Ajay is 50 meters apart from Vishal, then find the speed of Vishal.
    A 16 km/hr Correct Answer Incorrect Answer
    B 32 km/hr Correct Answer Incorrect Answer
    C 25 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 3x and 2x km/hr respectively. Distance covered by Vishal in 54 seconds = 2x x (5/18) x 54 = 30x m Distance covered by Ajay in 30 seconds = 3x x (5/18) x 30 = 25x m According to the question, => 30x – 25x = 50 => x = 10 Therefore the speed of Vishal = 2x = 20 km/hr
