The Correct Option is B

Solution and Explanation

- Statement I just tells us the total of Rs. 400 for the first four days of work, so the average daily wages of five days cannot be determined.
- Statement II states that the worker made 20% more each day, and we know that he earned Rs. 80 the first day. So we can calculate the wages for five days and hence the average. Hence, statement II alone is sufficient to answer the question.
Thus, the correct answer is (B).
