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.1 alone is sufficient while II alone is not sufficient
  • B.2 alone is sufficient while I alone is not sufficient
  • C.Either 1 or 2 is sufficient
  • D.Neither 1 nor 2 is sufficient

Answer: B

From 1, 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 2, total number of doctors in town

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

= 16 x 16 = 256.
