    A 196 Correct Answer Incorrect Answer
    B 357 Correct Answer Incorrect Answer
    C 301 Correct Answer Incorrect Answer
    D 273 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    L.C.M of (2, 3, 4, 5, 6) = 60
    So according to the first condition total number of toys with Akhil = 60p + 1
    Now according to the second condition, total number of toys = 7q
    Since number of toys is same hence, 60p + 1 = 7q
    When p = 5 then q = 43
    Therefore minimum number of toys = 60 X 5 + 1 = 301
