    Question

    Raj travels a certain distance at

    a certain speed in a certain time. However, if he had decreased his speed by 12 km/h, he would have taken 3 hours more. And, if he had further decreased his speed by 12 km/h, he would have been late by another 4 hours. Find the total distance traveled by him.
    A 3250 km Correct Answer Incorrect Answer
    B 2200 km Correct Answer Incorrect Answer
    C 2016 km Correct Answer Incorrect Answer
    D 1582 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the distance be ‘d’ km So, And, From (i) and (ii),

    Let original speed be S km/h

    [(S–12)×3]/12 = [(S–24)×7]/24 6(S–12) = 7(S–24) 6S–72 = 7S–168 S = 96 km/h Required distance = 96×(96–12)/12×3 = 96×7×3 = 2016 km
