Question: How many doctors are practising in this town ?

Statements:

1. There is one doctor per seven hundred residents.
2. There are 16 wards with each ward having as many doctors as the number of wards.

 [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

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.

 Irtiza said: (Jan 17, 2014) Wards refer to a single hospital: the question assumes that there are 16 wards in the entire town, which does not make sense, and is not mentioned in the answer option itself. The right answer should be D because we do not know the number of hospitals in the entire town.

 Ashutosh Kimothi said: (Jun 25, 2014) Question says how many doctors are practicing in town. By statement I one cannot find the town population to find the no: of doctors. By statement II one cannot assuming that there are only 16 wards in town which is not correct. By combining both statement also the No of Doctors cannot be assumed. The correct answer should be D as we don't know the population of town (referring the Statement I) and we don't know the No: of hospital in town or No: of wards in town (Referring statement II).

 Spandana said: (Feb 13, 2015) Till we don't sufficient information regarding the total number of wards in the whole town how can we calculate total number of doctors in whole town. So correct option should be option D.

 Venkat said: (Apr 7, 2016) How you gave the decision that is 256? There was not sufficient data.

 Harsh said: (Feb 20, 2017) Not given the total wards then how come?

 Sai said: (Jul 17, 2020) There is no sufficient information. Then how you calculate 256 doctors in the town?
