    Question

    Buses A and B are moving around a circular ground of

    radius 350 m. If the speeds of the buses A and B are 11 m/sec and 20 m/sec respectively, then what is the difference between the time taken by bus A and B to complete 2 round of the ground?
    A 180 Correct Answer Incorrect Answer
    B 176 Correct Answer Incorrect Answer
    C 132 Correct Answer Incorrect Answer
    D 165 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Circumference if the ground = 2πr = 2 × 22/7 × 350 = 2200 m So, distance = 2200 m  Time taken by bus A to cover 2 rounds of a ground = (2200/11) × 2 = 400 Time taken by bus B to cover 2 rounds of a ground = (2200/20) × 2 = 220 Required difference = 400 – 220 = 180
