So,folks here are the correct answers

Sentence Correction
The correct answer is A.

The original, while not a wonderful sentence, is not wrong. (B) omits the standard of judging benefit (general welfare). (C ) leaves aside all consideration of benefit and focuses only on the feasibility of the project. (D) is perhaps second best, though a little convoluted. However, it omits the certainty that the project could be accomplished. (E) incorrectly refers to the happiness of the individuals, while the original referred to the general welfare, which might not be the same thing at all.

Problem Solving
The correct answer is E.

Since the speed ratio of P and Q is 3:5, in the time P runs 300 m, Q runs 500 m. Hence in a 500 meter race Q can give P a head start of 200m. Thus both P and Q will finish the race at the same time
