Answer 1

The correct option is C

if the data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the questions.

It can be answered using statement 1 alone but not by 2nd alone.
Using the data in 1st statement and the question, we have
percentage of villas occupied = $\left(\frac{80}{100}\right)\times 100=80$
