    2. There are 16 wards with each ward having as many doctors as the number of wards.


  • Options
  • A. I alone is sufficient while II alone is not sufficient
  • B. II alone is sufficient while I alone is not sufficient
  • C. Either I or II is sufficient
  • D. Neither I nor II is sufficient
  • E. Both I and II are sufficient

  • Correct Answer
  • II alone is sufficient while I alone is not sufficient 

    Explanation
    From I, total number of doctors in town = (1/700 x N) , where N = total number of residents in town. But, the value of N is not known.

    From II, total number of doctors in town

    = (Number of wards in town) x (Number of doctors in each ward)

    = 16 x 16 = 256.
