   I ) They were originally 100 km apart
   II) Speed of a cycle A is 30 km / hr and speed of cycle B is 40 km /hr apart.
   
   If Statement I is sufficient for the answer.
   If Statement II is sufficient for the answer.
   If Statement I and II are sufficient for the answer but neither of the two alone is sufficient
   If Statement I or II is sufficient for the answer.
   both Statement I and II are insufficient for the answer.
   Option B
   Using the statement I we cannot answer the question because no speed is given.
   But using II we can.
   Since the cycles are going to meet 30 minutes , which means , the relative speed = 30 + 40 = 70 km/hr.
   So the gap = speed x time .So we can find the distance .Hence option B is correct.

   If Statement I is sufficient for the answer.
   If Statement II is sufficient for the answer.
   If Statement I and II are sufficient for the answer but neither of the two alone is sufficient
   If Statement I or II is sufficient for the answer.
   both Statement I and II are insufficient for the answer.
   Option D
   Clearly Y is greater than 60. Because average only increased if the value will be greater than 60.
   Also X denote s the number of children , so it will be the positive value. So by first statement we can get ( 1, 64), ( 2, 63) , ( 3, 62 ), ( 4 , 61) since y > 60.
   But by statement II Y is a prime number . So ( 4, 61 ) is correct.
   So 4 children with average weight 61are added in the group.
   Hence D is correct.

    If Statement I and II are sufficient for the answer but neither of the two alone is sufficient
    If Statement I or II is sufficient for the answer.
    both Statement I and II are insufficient for the answer.
    Option C
    As given in statements I and II, we have
    G = V = K,
    V + K + A = 64
    and A = V + k.
    take V + K = A in second,
    we get 2A = 64 or A = 32.
    Thus, V + K = 32 and V = K.
    So, V = K = 16. Thus, G = 16.
