Unable to add question to quiz

[MinalChauhan]

I'm not able to add questions to the quiz. Suppose I'm adding question 10 then after filling in all the question and answer details when I click on the Save button, the page shows Question added. But when I click on Back to Overview total number of questions is 9 only for that quiz.

I tried the Database repair option available in Global Settings but it's not helping out anyway.

Please suggest what could be the fix for this issue.
