So,folks here are the correct answers

Sentence Completion
The correct answer is B. The correct answer is parsimonious. The context provides a definition for the correct choice in is more than economical. The context also suggests the trait of being excessively frugal by the word so. Choices C and D would not apply because they mean poor, and the aunt is wealthy. Choice A is not excessive. E does not fit with the example of washing paper plates.

Problem Solving
The correct answer is A.

Kevin worked for a total of 10 days. So work done by Kevin is 10/25 = 2/5.
Hence the remaining 3/5 of the work is done by Robert in 5 days.
Thus, Robert alone can complete the entire work in 25/3 days.
