    riding back. He would have gained 40 min by riding both ways. How long would he take to walk both ways?
    A 110 min Correct Answer Incorrect Answer
    B 96 min Correct Answer Incorrect Answer
    C 100 min Correct Answer Incorrect Answer
    D 130 min Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    Let the time taken to ride one way be x and the time taken to walk one way be y. The time taken to walk one way and ride back is 1 hour and 30 minutes or 90 minutes. Then x + y = 90 By riding both ways he would have saved 40 min. Therefore, 2y = 90-40 = 50 y = 25 Therefore time taken to ride one way is 25 minutes We know, x + y = 90 or x = 90-25 = 65  Therefore time taken to walk one way is 225 minutes. The time taken to walk both ways is 65 ×2 = 130 minutes
