Question: How many doctors are practising in this town? Statements: There is one doctor per seven hundred residents. There are 16 wards with each ward having as many doctors as the number of wards.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
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.
