From Statement I we find that , total number of doctors in town = (1/700× R) , where R = total number of residents in town.
But, the value of R is not known.
From Statement 2 we can find that, the total number of doctors in town= (Number of wards in town) × (Number of doctors in each ward)= 16×16 = 256
Hence statement 2 alone is sufficient to answer the questions, while data in statement 1 is not necessary to answer the question.
