Final Exam Evaluation

In this problem, student A has completed his final exams in three subjects: Chinese, Mathematics, and English. There are two evaluation criteria at his school:

  1. Traditional Evaluation: The student passes if there is at most one subject with a score lower than 6060.

  2. Featured Evaluation: Each subject has a weight. The final score for a subject is computed as score (\times) weight. The overall score is the weighted average defined as:

[ \text{Overall Score} = \frac{score_1 \times weight_1 + score_2 \times weight_2 + score_3 \times weight_3}{weight_1 + weight_2 + weight_3} ]

The student is considered to have passed this evaluation if the overall score is not lower than 6060.

Given the scores and weights for each subject, determine whether the student passes both evaluation systems. Output Yes if he passes both criteria; otherwise, output No.
