Answer 1

To find the minimum percentage Diya must get in the seventh examination to get a grade of A, we need to consider the average scores of her first six examinations and the target average score of 95%. Statement 1 provides the necessary information to solve the question.

Step-by-step explanation:

To find out the minimum percentage Diya must get in the seventh examination to get a grade of A, we need to consider the average scores of her first six examinations and the target average score of 95%. Let's use the information given in the statements to solve this question.

1. Statement 1: The average score of Diya's first six examinations is 94.5%. This means the sum of her scores in the first six examinations is 94.5% times 6. Let's call this sum S. To get an average score of 95% in 7 examinations, the sum of her scores in all 7 examinations must be 95% times 7. Therefore, the score Diya must get in the seventh examination is (95% times 7) minus S.
2. Statement 2: All the tests carry equal maximum marks. This information doesn't provide any specific data about Diya's scores to help us determine the minimum percentage she must get in the seventh examination.

Since statement 1 provides the necessary information to solve the question, the minimum percentage Diya must get in the seventh examination to get a grade A is (95% times 7) minus the average score of her first six examinations.
