2560000 sequences of answers are possible.
<em><u>Explanation</u></em>
Total number of questions = 10
First 4 questions have 5 choices each and remaining (10-4)= 6 questions have 4 choices each.

and the possible sequences of answers for remaining 6 questions
Thus, the total possible number of sequences of answers = (625 × 4096) = 2560000
