In an examination, a student must answer 65% of the questions correctly to qualify. If a student answers 7 out of the first 14 questions correctly and qualifies, what is the minimum number of questions in the paper?

To find the minimum number of questions in the paper, we can set up the following equation:

(7 + x) / (14 + x) = 0.65

Solving for x, the minimum number of questions in the paper is 20.
