The ratio of the number of correct answers (C) to the number of wrong answers (W) is 3:1. Assuming there were 100 questions and the ratio stayed the same, Ray would've answered 75 questions.

How to determine the ratio?

First of all, we would calculate the number of wrong answers that were provided by Ray as follows:

Wrong answers = Total questions - Correct answers

Wrong answers = 40 - 30

Wrong answers = 10.

Therefore, the ratio of the number of correct answers (C) to the number of wrong answers (W) is given by:

C:W = 30:10

C:W = 3:1.

Also, the ratio of the number of correct answers (C) to the total answers (T) is given by:

W:T = 30:40

W:T = 3:4.

Assuming there were 100 questions and the ratio stayed the same, Ray would've answered:

Answer = 3/4 × 100

Answer = 75 questions.
