Answer 1

Answer:

The minimum marks she should score = 65 marks

Step-by-step explanation:

The marks scored in the first 2 tests were 65 marks

To make the average as 65, she should try and score 65 marks on the third test as well

⇒ 65 + 65 / 2 = 65

⇒ 65 + 65 + 65 / 3 = 65

∴ To keep the average 65, she should score 65 marks on the upcoming test
