Show answer & explanation
Correct answer: B
Conclusion: Statement II alone is sufficient to determine the number of doctors; Statement I alone is not sufficient.
Why the ratio in Statement I is insufficient: Statement I provides the ratio 1 doctor per 1000 villagers, but it does not give the village population. Without the population, you cannot compute the total number of doctors.
Why Statement II is sufficient: Statement II says there are 20 wards and each ward has a number of doctors equal to the total number of wards. Therefore each ward has 20 doctors.
Calculation of total doctors: 20 wards × 20 doctors per ward = 400 doctors
Final statement: Statement II alone determines the exact number (400). Statement I does not provide enough information by itself and is unnecessary once Statement II is known.
