Answer:

3 question papers

Step-by-step explanation:

If the teacher takes 15 minutes to mark 1 question paper. Then they will probably take 30 minutes to grade 2 question paper. Because 15 minutes+15 minutes=30 minutes. Then if you and another 15 minutes which will be 40 minutes because 15 minutes+15 minutes+15 minutes=40 minutes.

Hence, the teacher will mark 3 question papers in 40 minutes
