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.
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.
