Answer 2

Answer:

5 wrong answers

Step-by-step explanation:

Number of correct answers = 15 (given)

Score for 1 correct answer = 5 marks (given)

∴ Score earned from correct answers only = (15 × 5) = 75 marks

But she scored 65 marks

∴ Marks deducted = (75 – 65) = 10 marks

Let she answered n questions wrong.

∴ Negative marks (marks deducted) = 2n

As per question,

2n = 10

∴ n = 5

∴ Rosy answered 5 questions wrong
